Enantioconvergent chemoenzymatic synthesis of (r)-gamma-amino-beta-hydroxybutyric acid ((r)-gabob)

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.
