Definitions

  • This invention relates to a chemical process for the preparation of 3-substituted thiophenes, which are useful as intermediates in the production of penicillins and cephalosporins.
  • This cyclisation process may be carried out in a wide range of solvents subject to the solubility of the source of nucleophilic sulphur. It is often convenient to use a polar solvent, preferably a water-miscible solvent such as, for example, tetrahydrofuran, acetone, dimethylformamide, dimethylsulphoxide, hexamethylphosphoramide, acetonitrile, dimethoxyethane, dioxan, or an alcohol such as methanol, ethanol, propanol, butanol, in particular ethanol.
  • Preferred solvents include tetrahydrofuran and acetone.
  • An organic solvent such as methylene dichloride may also be employed.
  • the reaction may be carried out at ambient to elevated temperature depending on the particular reagents used and the values of X, Y, R 1 and R 2 .
  • suitable temperatures for the process are from -20°C to 100°C, preferably 10° to 50°C.
  • nucleophilic sulphur is for example the bisulphide ion, HS-
  • the bisulphide ion for the process of this invention may be provided by using a salt of this ion, preferably an alkali metal salt for example sodium bisulphide NaSH, which may be prepared, optionally in situ in the reaction, from sodium sulphide Na 2 S and sodium bicarbonate.
  • a salt of this ion preferably an alkali metal salt for example sodium bisulphide NaSH, which may be prepared, optionally in situ in the reaction, from sodium sulphide Na 2 S and sodium bicarbonate.
  • An alternative, and preferred, source of the bisulphide ion comprises hydrogen sulphide and a base, which again produces HS- in situ.
  • This combination of reagents has the advantage that the base employed can be the same as that used for the cyclisation process itself.
  • Suitable bases which may be employed to provide the basic conditions for the process of this invention include inorganic bases, such as alkali metal hydroxides, preferably potassium hydroxide, and alkali metal bicarbonates preferably sodium bicarbonate and organic basis such as substituted amines for example tri(C 1-6 )alkylamines such as trimethylamine or triethylamine.
  • inorganic bases such as alkali metal hydroxides, preferably potassium hydroxide, and alkali metal bicarbonates preferably sodium bicarbonate and organic basis such as substituted amines for example tri(C 1-6 )alkylamines such as trimethylamine or triethylamine.
  • the bisulphide ion may also be generated in situ from sulphurated sodium borohydride, NaBH 2 S 3 .
  • reaction of compound (II) with an alkali metal bisulphide produces an intermediate of formula (IV): Addition of further bisulphide (or presence of excess initially) removes a proton to give structure (III) above which then cyclises.
  • Another way of providing the basic conditions required for the process is to produce the intermediate ion of formula (III) directly which can then act as its own base for cyclisation. This may be achieved for example by treating compound (II) with an alkali metal sulphide, in particular sodium sulphide Na 2 S. Because the sulphur ion in such a compound has a double negative charge, S 2- , the intermediate formed after nucleophilic attack on compound (II), is structure (III) rather than structure (IV). No further base need then be present to complete the cyclisation.
  • the compounds of formula (II) are novel compounds and are the subject matter of copending European Patent Application No. 80105285.3, which is a divisional of the present application.
  • the group X should be readily displaced by nucleophilic attack by sulphide ions.
  • groups include chloride, bromine, hydroxyl, arylsulphonyloxy such as benzenesulphonyloxy, p-toluenesulphonyloxy, or p-nitrosulphonyloxy, alkylsulphonyloxy such as methanesulphonyloxy or C 1-6 alkanoyloxy such as acetoxy, propionoxy or butyroxy.
  • the group Y may be, for example, chlorine, bromine, hydroxy or C 1-6 alkoxy such as methoxy, ethoxy, or propoxy.
  • X and Y are halogen, especially chlorine.
  • the radicals R 1 and R2 in compound (II) are chosen according to the requirements of the compound (I).
  • the group R 1 should be carboxylic acid group or a group which may be converted to a carboxylic acid group or a functional derivative thereof for acylation the amino group of the penicillin or cephalosporin nucleus.
  • the R 2 group is chosen to provide the required a-substituent, or a precursor thereof, for the side chain of a penicillin or cephalosporin.
  • R 1 may be an ester group ⁇ CO 2 R 3 wherein R 3 is an alkyl, cycloalkyl, alkenyl, alkynyl, aryl or heterocyclic group, any of which may be substituted. Suitable such R 3 groups include:
  • Preferred groups for R 3 include C 1-6 alkyl, benzyl, phthalidyl, indanyl, phenyl, mono- di-, and tri-(C 1-6 )-alkyl substituted phenyl such as o-, m or p methylphenyl, ethylphenyl, n- or iso-propylphenyl, n-, sec-, iso- or butylphenyl.
  • Suitable groups R 2 include hydrogen, C 1-6 alkyl, such as methyl, ethyl, propyl, or butyl, benzyl, phenyl, alkyiphenyl, napthyl, a 5- or 6- membered heterocyclic group containing one or more sulphur and/or nitrogen and/or oxygen atoms in the ring and which may be substituted by an alkyl group having from 1 to 3 carbon atoms, for example thienyl, imidazolyl, thiadiazolyl, isoxazolyl, methylisoxazolyl, tetrazolyl, methyltetrazolyl, pyrimidinyl, pyridyl, pyrazinyl, pyrrolidyl, piperidyl, morpholinyl, thiazinyl, furyl, or quinolyl: a carboxylic acid group, a carboxylic ester group -CO Z R 3 as defined above, or a
  • R 1 and R 2 may conveniently both be carboxylic acid or ester radicals. It is convenient to prepare a diester compound of formula (I), i.e. where R 1 and R 2 both represent a group -CO Z R 3 , and then half-saponify in order to produce the compound (I) wherein one of R 1 and R 2 is a carboxylic acid group, suitable for coupling the penicillin or cephalosporin nucleus.
  • the group R 3 may be chosen according to the eventual penicillin or cephalosporin required.
  • the compounds of formula (I) in which one of the groups R 1 and R 2 represents a carboxylic acid function may be converted to a penicillin or cephalosporin by an method known per se, for example as described in British Patent Specification Nos. 1,004,670, 1,125,557, 1,133,886, 1,193,302, W. German OLS No. 2,600,866.
