Lipase B from Candida antarctica (CAL-B) catalyses the highly enantioselective (E > 200) transesterification of some 1-biaryl-2-yl-, -3-yl-, and -4-ylethanols and -propan-1-ols, as well as 1-(o-, m-, and p-pyridylphenyl)ethanols, 6, with vinyl acetate, Kazlauskas rule being obeyed in all cases. meta

✦ Synopsis
The enantiomer selectivity of the kinetic resolution of phenylethan-l,2-diol [(RS)-I] by sequential acetylation with vinyl acetate in the presence of lipase from Pseudomonas cepacia (Amano PS) was investigated for dependence on the solvent. Optimal conditions for the resolution of (RS)-I are presented.
