Definitions

  • the present invention relates to a synthesis process and compounds obtainable thereby.
  • Aldol reactions are one of the essential carbon / carbon linking reactions both in nature and in the repertoire of the synthetic chemist. In nature, such reactions are catalyzed by enzymes that function either via an enamine mechanism (class 1 aldolases) or via a zinc cofactor (class 2 aldolases). Here a high stereoselectivity is achieved.
  • Marek Majewski et al. describe in J. Org. Chem. 65 (2000) 5152-5160 a process for the aldol reaction of enolates starting from 1,3-dioxan-5-ones by reaction with chiral lithium amides.
  • R substituted or unsubstituted alkyl, aryl, heterocycles containing one or more O, N, S, P or B;
  • Ri and R 2 independently of one another are H, substituted or unsubstituted alkyl, Aryl, heterocycles containing one or more O, N, S, P or B
  • R ' H, OH, OR or OSiX 3 where X are independently alkyl or aryl.
  • a cyclic starting compound namely derivatives of 1,3-dioxan-5-one, is used, which are reacted with aldehydes in the presence of proline or proline derivatives.
  • These starting compounds are dihydroxyacetone derivatives. High stereoselectivities are achieved.
  • proline or proline derivative forms an enamine intermediate, in which the carboxy group of the proline is involved in the orientation, so that the surprisingly high stereoselectivities are achieved.
  • Alkyl in the sense of this application are in particular straight-chain or branched alkyl, cycloalkyl, bicycloalkyl, tricycloalkyl, alkenyl, alkynyl, heterocycloalkyl compounds. Typical representatives are methyl, ethyl, N-propyl, isopropyl, butyl, cyclohexyl or substituted derivatives thereof.
  • Aryl in the sense of this application also includes, in particular, heteroaryl, arylalkyl or heteroarylalkyl groups. Typical representatives are phenyl, benzyl, pyrridine and substituted derivatives thereof.
  • the alkyl or aryl radicals can also be substituted by one or more hydroxy, alkoxy, aryloxy, alkanoyl, aroyl, carboxy, alkoxycarbonyl, amino, alkylamino, hydroxylamino, amido, carbamoyl , Ureido, amidino, guanidino, cyano, azido, mercapto, alkylthio, alkylsulfoxy, alkylsulfonyl, alkylsulfonyl, aminosulfonyl, fluorine, chlorine, bromine, iodine, alkyl or perfluoroalkyl radicals substituted derivatives.
  • R contains one or more nitrogen atoms.
  • nitrogen atoms are derivatives of compounds with, for example, azididine, pyrrolidine, pyrroline, piperidine, piperazine, homopiperazine, morpholine, thiomorpholine, pyridine, di- or tetra-hydropyridine, pyrimidine, Pyrazine, azepine, dihydroazepine, oxazepine, diazepine, imidazole, pyrazole, oxazole or Thiazole rings, which may have fused-on aliphatic, heteroaliphatic, aromatic or heteroaromatic rings and / or by one or more hydroxy, alkoxy, aryloxy, aklanoyl, aroyl, carboxy, alkoxycarbonyl, amino, alkylamino -, Hydroxylamino, amido, carbanoyl, ureido, amidino, guanidino, cyano, azido
  • the amounts of proline or proline derivative required for the reaction are typically 0.1 to 30 mol%, more preferably 1 to 10 mol%, even more preferably 1 to 5 mol%.
  • proline or proline derivative used only catalytically participates in the reaction and can therefore in principle be recovered.
  • reaction is carried out using L-proline.
  • D-proline is typically used to obtain the compounds 2, 4.
  • 4-hydroxyproline or a protected precursor thereof can also be used.
  • the ratio of the formation of anti (1, 2) or syn (2, ⁇ 4) compounds depends on the component of structural formula 6.
  • the reaction is carried out in an aqueous solvent.
  • the proportion of water is then preferably more than 50% and even more preferably more than 90%.
  • reaction is carried out without a solvent.
  • Particularly suitable solvents are trifluoroethanol and formamide, both optionally mixed with water.
  • the water content is preferably below 20%.
  • Other suitable solvents are DMSO and DMF. Mixtures of these solvents can of course also be used.
  • radicals R are those in which R is -CH (OH) -CH 2 -N 3 (R or S) or 6
  • the invention further relates to the use of compound 5 as a reagent for an aldol reaction.
  • the invention further relates to compounds of the general formula
  • R substituted or unsubstituted alkyl, aryl, heterocycles containing one or more O, N, S, P or B;
  • Ri and R 2 are independently H, substituted or unsubstituted alkyl, aryl, heterocycles containing one or more O, N, S, P or B.
  • the substances according to the invention which can be obtained in high stereoselectivities on the new synthetic route, are particularly suitable as starting or intermediate products in the synthesis of carbohydrates and aza-carbohydrates. Therefore the use of the compound according to the invention as an intermediate in the synthesis of carbohydrates or Aza carbohydrates Subject of the invention.
  • the dihydroxyacetone backbone is recovered. If necessary, this can enter into ring closure reactions coupled with the rest coupled through the aldol reactions. In embodiments in which R contains an amine, this can be used to form aza sugars or amino sugars.
  • L-proline produced both the anti and the syn product. They could be separated chromatographically and showed the following NMR spectroscopy data.
