Chiral resolutions of carboxylic acids (1-3) and alcohol (4) were carried out through esterification or transesterification in organic solvents using cross-linked enzyme crystals (CLEC(R)) of Candida rugosa lipase (CRL). Comparison of these results with those of elude CRL reveal significant differences. As was seen in resolution through hydrolysis,(1) a marked improvement in enantioselectivity is realized with the CLEC. Additionally, the stability afforded the enzyme in CLEC form leads to a higher activity in organic solvent. Copyright (C) 1996 Elsevier Science Ltd
