摘要:The present invention is a method for the stereoselective straightforward synthesis of gamma-acyloxy carboxylic acids of novel structure starting from racemic gamma-hydroxy carboxylic acid salts that are obtained by alkaline hydrolysis of the racemic gamma-lactones. The salt is acylated by enzyme catalysis in an organic solvent containing an acyl donor and an immobilised lipase, on stirring at room temperature (ca 20 °C) until reaching the conversion rate required. After that, the reaction mixture is acidified and extracted and the product treated with catalytic amount of para-toluenesulfonic acid in toluene during the time required for the relactonisation of the unreacted salt enantiomer. Thereafter, the target gamma-acyloxy carboxylic acid formed from one enantiomer of the starting compound and relactonised gamma-lactone formed from the other, unreacted enantiomer of the starting compound are isolated using a routine separation method, such as distillation, extraction with NaHCO3 water solution followed by acidification or column chromatography.

摘要:The present invention relates to a novel biocatalytic process for the stereoselective preparation of alpha amino amide compounds catalyzed by NHase enzymes. A further aspect of the invention relates to novel NHase enzymes as well as further improved NHase enzyme mutants, nucleic acid molecules encoding these enzymes, recombinant microorganisms suitable for preparing such enzymes and mutants. Another aspect of the invention relates to a chemo-biocatalytic process for the preparation of lactam compounds comprising the new catalytic process for the preparation of alpha amino amide compounds catalyzed by NHase enzymes, as well as the chemical oxidation of the alpha amino amide by applying certain chemical oxidation catalysts suitable for converting the alpha amino amide under retention of its stereochemical configuration to the respective lactam. The novel chemo-biocatalytic process is particularly suited for the synthesis of valuable pharmaceutical compounds, like in particular (S)-Levetiracetam.
