Lipase-catalyzed enantioselective hydrolysis of the acetic ester of racemic α-cyano-3-phenoxybenzyl alcohol (CPBA) was examined to prepare (S)-CPBA. Most of the lipases tested hydrolyzed (S)-CPBA acetate preferentially, while Candida cylindracea lip

A simple and general synthetic method is described for erythro- and threo-forms of 2-amino-1,3-diols with an acyclic terpenoid-type side chain. 13C-NMR data are given for the triacetyl and N-acetyl derivatives of the synthetic erythro- and threo-2-am
