Abstract

A kinetic resolution of racemic pyridyl and bipyridylethanols was performed by Candida antarctica lipase with vinyl acetate in diisopropyl ether, in which ( R)-alcohol was acetylated stereoselectively, and both the acetate 2 and the remaining ( S)-alcohol 1 were obtained with high enantiomeric excesses. ( S0-Oligopyridylethanols, 7 and 8 were prepared by a coupling reaction of ( S)- 1b and ( S)- 1e with ethyl bipyridyl sulfoxide.
