摘要
Enantioselectivities near maximum values were obtained in the catalytic reaction by a rapid addition of a fluorous achiral alcohol (Rfh(3)C-OH) to the reaction mixture:for DHPEX in Rfh(3)C-OH/THF solid-liquid biphase system and for a fluorous chiral alcohol in THF/FC-72 liquid-liquid biphase system.
