PESTICIDE COMPOUNDS, COMPOSITIONS AND PROCESS FOR THE PREPARATION THEREOF

This invention relates to alkynyl pesticide compounds of the general formula I., pesticide compositions containing the active ingredients of general formula I., furthermore the pesticide synergists of general formula I., and synergized pesticide compositions with known pesticide active ingredients, and the process for the preparation thereof.

In general formula I the substituents have the following meanings:

Ar = an alycyclic-, aromatic-, or one or more heteroatom containing heterocyclic moiety, optionally substituted by one or more alkoxy, methylenedioxy, alkyl, halogen, haloalkyi or nitro group, and/or condensed with a benzene ring,

R¹ , R² = independently hydrogen, alkyl, alkenyl, haloalkyl, phenyl, substituted phenyl, cycloalkyl,

R³, R⁴ = independently hydrogen, alkyl, alkenyl, haloalkyl, phenyl, substituted phenyl, cycloalkyl, or

R³, R⁴ are together =O;

Y= C, =PO, or Y R³ R⁴ form together a

group;

X = -O-; -NR¹⁰-;

R⁹ = hydrogen, alkyl, phenyl, substituted phenyl;

R¹⁰ = hydrogen, alkyl;

R⁵, R⁶, R⁷, R⁸ are independently hydrogen, alkyl, alkenyl, haloalkyl, or

Ar-(CR ¹ R²)_m-( YR³R⁴)_n-X- form together a carboximide group;

E = hydrogen, halogen, methyl;

m = 0, 1 , 2;

n = 0. 1 ;

o = 0, 1 , 2;

p = 0, 1 , 2, with the proviso that the sum of the atoms or groups of the bridge -(CR ¹ R²)_m-

(CR³R⁴)_n-X-(CR⁵R⁶)_o-(CR⁷R⁸)_p is 3 and the -C=C-E sceleton w ith the atoms of the bridge forms a linear chain, consisting of 6 atoms ending favorably in a methy 1 group.

furthermore with the proviso that if Ar is naphthyl group. Y means C-atom. X means O-atom. R³ and R⁴ together can not mean =O .

The invention includes furthermore the salts and the optically active isomers of the compounds of general formula I.

Narrower groups within compounds of general formula I. are representated by the compounds of general formula IA, IB, IC, ID, IE, IF, their salts and optically active isomers, where the meanings of the substituents are the same, as defined above.

Favourable representatives of the compounds of general formula I. are:

1 -naphthyl-methyl 2-butynyl ether,

2-propynyl- 1 ,3-benzodioxol-5-carboxylate,

1-[(2-butynyloxy)-ethyl]-3,4-dimethoxybenzene.

2,6-dichloro-1-(2-butynyloxymethyl)benzene,

1 -[ 1 -(2-butynyloxy)propyl]naphthalene,

R-(+)-2-[ 1 -(2-butynyloxy)ethyl]naphthalene,

5-[(but-2-ynyloxy)methyl]-1 ,3-benzodioxole.

5-[2-methyl- 1-(2-butynyloxy)propyl]-1,3-benzodioxole.

5-[(but-2-ynyloxy)phenylmethyl]-1,3-benzodioxole,

2-[(2-butynyloxy)methyl]- 1 ,4-benzodioxane.

2,3-dihydro-2,2-dimethyl-7-(3-pentyloxy)benzofuran

In the term Ar the aromatic group is favourably phenyl or naphthyl group.

Ar as a heterocyclic moiety may contain one or more O, S, N heteroatoms, it may favourably represent benzodioxole-, benzodioxane-, 2-benzofuran-, 7-benzofuran-moieties. The alicyclic group may favourably be condensed with a benzene ring, thus for instance may represent indane group, or 1,2,3,4-tetrahydronaphthyl group. The carboximide group may favourably represent phthalimide moiety.

The aromatic, heterocyclic and alicyclic Ar groups are optionally substituted by C_1-4 alkoxy-, methylenedioxy-,C_1-4 alkyl-, halogen-, C _1-4 haloalkyl- or nitro group.

Compounds which are non-toxic, or only slightly toxic alone, but given together with a pesticide, preferably arthropodicide agent they enhance markedly the potency of the latter, are called synergists. These materials may in principe act in several ways, however they exert their effect decisively by blocking the metabolism of the active substance. Metabolism may proceed via oxidative. hydrolytic. conjugative and absorption reactions and by the variations thereof.

At present there is no unambiguos example for a synergist acting at the receptor level, neither do they play an important role in the praxis.

The synergistic potency e.g. in the case of insecticides is characterized by the so-called SR synergist ratio which is given as follows:

The more the SR₅₀ value differs from 1 , the higher is the synergistic potency.

The use of synergists in arthropodicidal preparations is very attractive, since they afford a possibility to come out with new preparations with practically all representatives of the area. These new preparations, compared to the previous ones, promise to be less expensive, less toxic, more selective, encountering less environmental hazard, suppressing the evolution of resistance, and being active also on strains which already evolved resistance.

Following the discovery of synergists and the reveal of their mode of action, a wide-range research and development work started from the mid 60-ies till the late 70-ies to work out new synergists. This research, however resulted only a few molecules which really attained application (at present the number of the registered insecticide synergists is less than 10). These compounds are of basic scientific importance in the research of resistance ( K. F. Raffa and T. M. Priester. J. Agric. Entomol., 2( 1 ), 27-45, ( 1985)), however, there are only 2-3 molecules listed as products in the Pesticide Manual, and only two materials (PBO. MGK264) which are actually on the market. The field application has been restricted by several factors: it is not easy to find a chemical tool which can be used selectively and safely, and the cost/effectiveness ratio of which is competitive with that of the active ingredient. To apply a synergist

economically, it must be highly potent, it must act at small doses (not exceeding the original dose of the active ingredient).

On the basis of their chemical structures the presently known arthropodicide synergistic compounds may be divided into the following groups:

### 1,3-methylenedioxyphenyl (MDP) derivatives

### O-2-propynyl and propynyl-homologues and their derivatives (ethers, oxim-ethers, esters)

### N-alkyl derivatives

### phosphor esters

### other derivatives e.g. thiocyanates, polyhaio ethers etc.

The compounds may also be divided into groups on the basis of their target of attack [K. F. Raffa and T. M. Priester, J. Agric. Entomol., 2( 1 ), 27-45, ( 1985)], but this grouping is rather theoretical, less exact, first of all because the actual metabolic processes are not fully known. The metabolism of most of the compounds proceeds consecutively, but may also proceed simultaneously, and may follow several mechanisms, thus the division is less informative, even if we consider the first step of the cascade degradation as the decisive step.

For the metabolic degradation of most arthropodicides first of all the oxigenaze system is responsible. It is agreed in the literature that the compounds of this group exert their activity basically by blocking the cytochrome P-450 enzyme of the microsomal oxidation system [John E. Cassida. J. Agr. Food Chem., 18(5), 753-772, ( 1970), R. M. Sacher, R. L. Metealf and T. R. Fukuto: J. Agr. Food Chem., 16(5). 779-786. ( 1968)]. The enzymes forming the structurally analogous group of so-called isoenzymes constitute the major part of the detoxificaton system of the organisms [Ortiz de Montellano. P. R., Ed.

Cytochrome P-450: Structure Mech. and Biochem., Plenum New York. ( 1986)]. They perform detoxification via mono-oxigenation of the substrate, producing a more polar product, which possibly after further transformations can be eliminated by the organism. The system degrades very different structures by the same way. Therefore they are also designated as Mixed Function Oxigenazes (MFO) and Polysubstrate Monooxigenazes (PSMO).

On that basis one could expect that the surface of the enzyme is aspecific for the synergist. too. Quite the contrary, we have found that the compounds may be optimized.

For the isolation and testing of the Cytochrome P-450 enzymes of insects there are standard methods available [J. G. Scott and S. S. T. Lee; Arch. Insect Biochem. and Phys., 24, 1-19, (1993)]. The enzymes of various species may show great similarities, but they may also differ significantly from each other. The synergists known from the literature and investigated by us belong to the group of O-2-propynyl, and propynyl-homologues and their derivatives (ethers, oxim-ethers. esters). As shown by the literature they exhibit different potency for the different species, which means that the oxidation capacity of the species varies to a certain extent. This is the reason for the high insect/mammal selectivity and synergist selectivity, characteristic for that group of compounds. These selectivities. which cannot be directly explained by the above mode of action, are the bases of the development and safe application. On the other hand this is the reason why these compounds have not became commercially available. For all the compounds of the group prepared and evaluated so far we can tell, in general, that their effect was exlusively bound to the propynyl side-chain, this chain has been substituted in the allylic position by various aryl rings mainly through an oxygen atom. The compounds known as yet may be divided into the following groups:

### Phenyl propargyl ethers [Fellig et. al., J. Agr Food Chem.. 18(5). 78.

( 1970)]

### Benzyl propargyl ethers [Ciba Geigy. Ger. Offen. 2 235 005 ( 1972)]

### Benzaidoxime propargyl ethers [Ciba Geigy, Ger. Offen, 2 016 190

( 1970)]

### Naphthoic acid propargyl esters [Hoffman-La Roche. Belg. Patent.

867 849 ( 1978)]

### Alkynylphthalimides [FMC, Ger. Patent, 1 217 693 ( 1966)]

### Phenylphosphonic acid propargyl esters [Niagara Chem. Div., FMC

Corp.. Technical Data Sheet on NIA 16824. ( 1968)]

The first two groups are sub-divided into further groups owing to the high variability of the aromatic group and its substituents. Thus, there are known naphthyl propargyl ethers [Hoffman-La Roche, US 3 362 871 ( 1968); Ciba

Geigy, Ger. Offen, 2 100 325 ( 1971 )],

4-hydroxyquinoline propargyl ethers [Alkaloida, HU 210 557, ( 1992)], methylenedioxybenzyl propargyl ethers [Sumitomo. JP. 03 01177, ( 1973)] and alfa-substituted methylenedioxybenzyl propargyl ethers [Sumitomo. JP,

61 24585, 61 24586 ( 1986)].

In a study about naphthyl propynyl ethers it has been concluded that butynyl ethers, first of all 3-butynyl ethers are more potent than the analogous propargyl and pentynyl ethers [R. M. Sacher et. al., J. Agr. Food Chem.. 16, 779-786,

( 1968)]. Interestingly, however there was no continuation of that work, the discovery has not been patented, either. Detailed analysis of the literature data suggest, that the propynyl side-chain cannot be replaced by homologous chains. since the publications and patents relate further on to propargyl derivatives.

In order to clear this contraversion we have prepared the compounds in question, and found that in contrast to what was disclosed in the literature, the 2-butynyl derivative (the one ending in a methyl group) is more potent than the 3-butynyl derivative; the alpha-isomers are more potent than the analogous beta- isomers; and the 3-pentynyl derivative is more potent than the 2-butynyl derivative. These data suit well in our theory, and the data given in the literature might be the reason why this direction was not followed by others.

Similarily. there is a contraversion regarding the activity of the 4-pentynylphthalimide derivatives: although they proved to be potent synergists of allethrin. they antagonized with pyrethrin [H. Jaffe. J. L. Neumeyer, J. Med. Chem.. 13, 901 , ( 1970)]. In these structures again, the alkynyl chain ends in triple bond. The hybride variations of these structures, namely the N-alkyloxy-O-propargyl-phthalimides have also been prepared, here again the triple bond is in terminal position [Sumitomo, NL, 6 600 916 ( 1966)].

To sum up. the most active representatives of the group, although on some tests exhibited outstanding activity, and were superior regarding their synergist/active ingredient ratio [D. J. Henessy, Biochemical Toxicology of Insecticides, Ed., R. D. O'Brian & I. Yamamoto, Academic Press, 105-1 14, ( 1970)], have never been applied in the praxis. This has several reasons: their activity did not reach the potency of earlier, well-established derivatives, they exhibited activity only in a narrow range, their potency was highly species-dependent, and within one species it depended greatly on the "strength" of the individual. Their safe and broad application was not therefore ensured.

The alkynyl compounds listed above are all derivatives of a common optimal structure, but the authors did not realize the relationships, and have not prepared the most active representatives, alloying and improving the advantages of these groups of compounds.

We have experimentally tested, compared and analysed the biological effect of the known compounds, as well as that of the new derivatives prepared by us, and revealed the structural element which is responsible for the effect. On that basis we have prepared new compounds which surpass significantly the activity of the earlier ones and combine those properties which ensure effectiveness on more species and with more known active ingredients.

The integral part of the present invention is the discovery, that in the optimal compounds the carrier of the activity is a triple bond of an alkynyl structure with an electron-rich Ar ring, which is connected to the triple bond through a mobile bridge consisting of three atoms. The atoms of the bridge are variable, and may have substituents, and so is the ring. To enhance the activity it is favourable to introduce lipophilic and electron-rich atoms and substituents. Thus the atoms of the bridge may be -besides of carbon atoms- oxigen, sulphur, nitrogen, and phosphor heteroatoms. These atoms may be linked through single or multiple bonds to each other and optionally with further substituents containing the above heteroatoms they may be substituted to further functional groups or derivatives. The atoms may be replaced by each other. The first element of the bridge may with its substituent form a ring, which may be attached to the aromatic ring, and thus may be part of the electron-rich moiety. Into the ring, linked to the bridge, heteroatoms, as listed above, may also be incorporated, and the effect may be further enhanced by the introduction of alkoxy, halogen, alkyl, haloalkyi or nitro substituents. The ring may be 5-, 6-, or 7-membered and may be condensed with a further ring, which is built according to the above principles, and may incorporate the first element of the bridge. Compounds in which the acetylenic hydrogen of the alkynyl side-chain is replaced by a methyl group exhibit higher activity than the the analogues with terminal triple bond. Keeping these rules we can carry out new substitutions by which we can modify the character of the compounds, according to the demand (lipophilicity. translaminarity, systemicity, etc.) of the application area.

Of the isomers of optically active compounds. e.g. α-methyl-substituted benzyl derivatives, the R(+)enantiomers are more potent than the S(-)enantiomers. The difference between the activities of the isomers is growing with an enhancing activity of the racemic mixture.

The compounds developed by us are new, they are characterized by outstanding mammal/insect selectivity and high potency, exerted at low dose related to the active ingredient. This is attributed to the outstanding high receptor affinity of our compounds. In comparative experiments the indices of our compounds highly surpassed those of earlier known synergists for active ingredients, whose metabolism is based on microsomal oxidation. This high activity and selectivity were also demonstrated in field studies conducted on small plots. The compounds did not show fito-toxicity, they did not separate from the active ingredients, their physico-chemical parameters fitted well with those of the active ingredient. Through these features the dose/efficacy/cost value, which earlier hindered the application, could favourably be modified and the application became possible.

Compounds of the general formula I can be most preferably used to synergize the effect of carbamates preferably carbofuran.

We have found that the compounds have dual action, they are superior synergists of arthropodicide active ingredients, and they also hinder the individual grows of arthropoda through an effect impeding the biosynthesis of ecdison, a material, playing key role in the growth of arthropoda. There is thus an unambiguous relationship between the synergistic- and the individual growth-hindering activities. This latter effect, beside the outstanding metabolism-blocking activity of the compounds, is also a consequence of the fact, that these materals, in contrast to the other, earlier known families of compounds, practically do not degrade, or degrade only extremely slowly in the organism of the arthropoda. Thus, when applied alone, at a long run. depending on the periods of the endocrin regulation, they are able to block the hormon synthesis and hinder the degradation of the endo and exo-biotica. Due to the toxines accumulating in the organism, the individuals become incapable of living, they do not eat. the production of eggs deminishes. and the reproduction stops.

Beside these enhanced activities, the toxicity values of the compounds on mammals did not increase. This can be attributed to the differences in the electrode potencial values of microsomal oxidation systems for mammals and for arthropoda. Whereas the oxidation potential values of the higher-order organisms are high, and therefore they are able to beat the eiectron-barrier of the complexed synergists, the oxidation system of the arthropoda, with its small potential, is not capable to oxidate, and by this to remove the complexed molecule from the surface of the enzyme, causing the paralysis of the system. This is the reason why the compounds can be applied safely and selectively. The over-average fast degradation and excretion of the compounds from mammalia, owing to their high enzyme activity and fast enzyme binding, ensure . in contrast to the arthropoda. that these materials do not enhance the effect of biotics found or taken up by the mammalian organism, and therefore they are safe.

The effect was demonstrated by us on various arthropode species. Applied alone, or as a synergist. the compounds were active on insects, plant-louses and also on acari. In the light of the above, this fact refers again to the qualitatively different detoxification system of the mammals.

A very valuable advantage of our compounds is that on applying them to species, which already evolved resistance, the toxic dose could be reduced below the original dose of the known active ingredient (measured on susceptible strains). This has not been experienced with other synergists. This makes possible the safe and effective management of resistent populations, complying with the modern regulations.

Beside the expected advantages mentioned above (they make possible to develope tools which are less expensive, less toxic on mammals, selective, and can suppress resistance) with the help of these compounds a number of well-established active ingredients can be renewed, the market of which has fallen back in the past years, because resistance evolved against them. (Carbofuran. Quinalphos, Cartap, Methomyl). Our compounds create new application and market possibilities, since they enhance the potency of less active materials (Resmethrin, Bioallethrin, Pirimicarb etc.) to the levei of the most active compounds, without increasing their toxicity. PBO. which is on the market in big lots, but -with natural resources running low- at increasing price, and which is drawing back because of its suspected tumor provoking effect, may also be replaced with the help of our compounds.
