Abstract

Enantiomerically pure (R)-2-naphthylmethoxyacetic acid (2-NMA) was synthesized from 2- naphthaldehyde via an integrated chemo-enzymatic procedure. The one-pot, successive use of SnBr2–TMSCN and AcBr worked effectively to give a racemic cyanohydrin acetate. Lipase from Burkholderia cepacia then mediated the highly enantioselective hydrolysis of the (S)-enantiomer of the racemate, leaving the (R)-acetate with an ee of> 99.9%. The ...
