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:Synthesis of 2-aralkoxyadenosines and 2-alkoxyadenosines
发明人：MOORMAN ALLAN R
权利人:KING PHARMACEUTICALS RES & DEV
摘要:The invention provides new methods for synthesis of 2-aralkyloxyadenosines and 2-alkoxyadenosines. The invention is particularly useful for synthesis of 2-[2-(4-chlorophenyl)ethoxy]adenosine. Preferred methods of the invention include activating a guanosine compound followed by hydrolysis; alkylating the hydrolyzed compound with subsequent animation to provide a 2-aralkyloxyadenosine or a 2-alkoxyadenosine compound.

标题:Synthesis of 6-aryl-4-aminopicolinates and 2-aryl-6-aminopyrimidine-4-carboxylates by direct suzuki coupling

摘要:Improved methods of synthesizing 6-aryl-4-aminopicolinates, such as arylalkyl and alkyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates and arylalkyl and alkyl 4-amino-3-chloro-5-fluoro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates, are described herein. The improved methods include a direct Suzuki coupling step, which eliminates the protection/de-protection steps in the current chemical process, and therefore eliminates or reduces various raw materials, equipment and cycle time as well as modification of other process conditions including use of crude AP, use of ABA-diMe, and varying pH, catalyst concentration, solvent composition, and/or workup procedures. This includes synthesis of 2-aryl-6-aminopyrimidine-4-carboxylates.
