Resolution of N-protected cis- and trans-3-aminocyclohexanols via lipase-catalyzed enantioselective acylation in organic media
摘要:
The enzymatic acylation of N-protected cis- and trans-1,3-aminocyclohexanols using lipases in organic solvents is described. By modifying certain reaction parameters Such as the solvent, the lipase and the N-protecting group, it is possible to achieve high enantioselectivities and to obtain enantiomerically pure 3-aminocyclohexanols. The influence of the N-protecting group and the conformation of the Substrate on the reaction rate was also Studied. (C) 2004 Elsevier Ltd. All rights reserved.
