Enantiomerically pure N-protected cis-4-aminochroman-3-ol (key precursor in the synthesis of novel HIV second-generation protease inhibitors), its trans isomer and both cis- and trans-1-amino-1,2,3,4-tetrahydronaphthalen-2-ol, useful chiral catalysts in organic synthesis, have been successfully prepared through a lipase-catalyzed kinetic acylation of the alcohol moiety, employing as substrates the corresponding N-benzyloxycarbonyl-protected derivatives. Of the biocatalysts tested, Pseudomonas cepacea and Candida antarctica B lipases showed excellent enantioselectivities in the acylation processes depending on the reaction conditions employed.
