Abstract
High enantioselectivity was achieved in the lipase-catalyzed kinetic resolution of 5-hydroxypyrrolidin-2-one and 5-hydroxy-1,5-dihydropyrrol-2-one derivatives. Lipase PS and Novozym 435 were the successful catalysts (E=>1000). The acetylation of the N-protected 5-hydroxy-1,5-dihydropyrrol-2-one derivative gave the (R)-acetate with high enantioselectivity, while, without N-protection, the (S)-acetate was obtained.
