专利号:US-2023183177-A1 优先权日:2020-04-24 标题:Enantioselective chemo-enzymatic synthesis of optically active amino amide compounds 发明人:GRILL BIRGIT; WINKLER MARGIT; SCHWAB HELMUT; STROHMEIER GERNOT; DONSBACH KAI; WALDVOGEL SIEGFRIED R; ARNDT SEBASTIAN; WEIS DOMINIK 权利人:PHARMAZELL GMBH 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.
