| titleOfInvention | PROCESS FOR THE PREPARATION OF CHEMICALLY HARD-ACCESSIBLE ORGANIC COMPOUND SPECIES |
| abstract | Parent patent discloses a process for preparing difficulty available or pure optical isomers of unsatd., cyclic, alpha,beta-dihydroxy-monocarboxylic acids; substd. unsatd., aliphatic dicarboxylic acids and substd. unsatd. aliphatic monohydroxy-dicarboxylic acids and lactones. In this addition, (+)-2,5-dihydro-4-methyl-, (I), and (+)-2,5-dihydro-2-methyl-5-oxo-furan-2-acetic acid (II) are prepd. by a cresol co-oxidn. process comprising: (a) cultivating a biologically active suspension of a Pseudomonas bacteria of strain B 13 on a mineral salt soln. contg. a 3-chloro-benzoate as only C- and energy-source; (b) adapting the bacterial strain to 4-chlorophenol by continuously replacing the 3-chloro-benzoate according to a linear gradient by an equimolar concn. of 4-chloro-phenol until constant cell density E564 = 1.8 is reached; (c) adding a cresol and co-oxidn. (I) is obtd. on adding o-cresol; (II) on adding p-cresol and a (I)/(II) isomer mixt. on adding m-cresol. The metabolites dissolved in culture liq. are recovered by sepg. the bacterial cells or by preparative chromatography. (I) can be prepd. in quantitative yields; (II) in 95% yield and the isomer mixt. in 73% and 14% yields of isomers (I) and (II). |
