摘要:
The present invention particularly relates to a chemoenzymatic process for the stereoselective preparation of both enantiomers of 3-hydroxy-4-trityloxy butanenitrile key intermediates for the preparation of (R)-GABOB by lipase mediated kinetic resolution of its racemates and their effective application in the enantioconvergent synthesis of (R)-GABOB.
摘要:
A chemoenzymatic process for the stereoselective preparation of both the (R) and (S) enantiomers of 3-hydroxy-3-(2-thienyl) propanenitrile has been developed. These optically pure key intermediates were prepared by enzymatic resolution of (±)3-hydroxy-3-(2-thienyl) propanenitrile both by transesterification and by hydrolysis reaction which were then transformed to both enantiomers of duloxetine.

摘要:
The present invention relates to a novel epoxide hydrolase enzyme which aims to achieve a high degree of resolution towards a broader range of substrates with high enantioselectivity and yields with minimal product inhibition. The invention further relates to a new bacterial strain Achromobacter sp. MTCC 5605 isolated from a petroleum-contaminated sludge sample, capable of producing the said enzyme. It is notable that the enzyme can be used as whole bacterial cell preparation, which allows continuous hydrolysis of substrates at even higher concentration and have an advantage of being recycled. The invention further relates to a process for the hydrolysis of different aryl epoxides which are potential synthons of intermediates for the synthesis of chiral amino alcohols and bioactive compounds like β-blockers.
