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.

标题 :Efficient procedure for the synthesis of hydrazone-linked tetrahedral nanocages
发明人：SCHNEEBELI SEVERIN; VESTRHEIM OLAV
权利人:UNIV VERMONT
摘要:The present application is directed to a nanocage of Formula (I): wherein A and R are as described herein. The present application is also directed to an efficient process for preparation of a nanocage of Formula (I), which allows for efficient scale-up of the nanocage synthesis. Furthermore, this new process allows for rapid nanocage diversification, due a newly introduced late-stage functionalization method.
