摘要:
The lipase catalyzed resolution of cis and trans-3-amino-4-hydroxytetrahydraurans and cis-3-amino-4-hydroxypyrrolidines have been studied. For all the heterocycles, the best enantioselectivity was obtained using Candida antarctica lipases A and B as catalysts in hydrolytic processes. The absolute configuration of the optically pure obtained heterocycles has been assigned. (C) 2014 Elsevier Ltd. All rights reserved.
