  Polymeric salen-Ti(IV) or V(V) complex catalyzed asymmetric synthesis of O-acetylcyanohydrins from KCN, Ac2O and aldehydes

  摘要：

  Polymeric salen-Ti(IV) and V(V) complexes were employed in the enantioselective O-acetyl cyanation of aldehydes with potassium cyanide and acetic anhydride. The crosslinked polymeric salen-Ti(IV) catalyst exhibited good activities and enantioselectivities, up to 91 % ee with 99 % conversion was obtained at -20degreesC with 1 mol % of catalyst (based on bimetallic catalytic unit). Moreover, six consecutive recyclings with the easily recovered crosslinked polymeric catalyst showed no obvious decrease in either activity or enantioselectivity. Linear polymeric salen-V(V) catalyst showed good catalytic efficiency too, up to 94 % ee with 99 % conversion was obtained at -42degreesC with 5 mol % of catalyst. (C) 2004 Elsevier Ltd.

  Crosslinked polymeric salen–Co(III) complexes derived from a novel dialdehyde and a trialdehyde were synthesized and employed in the hydrolytic kinetic resolution (HKR) of terminal epoxides. Up to 99% ee were obtained with only 0.16–0.02 mol% of catalyst (based on catalytic unit).

  合成了衍生自新型二醛和三醛的交联的聚合物Salen-Co（III）配合物，并将其用于末端环氧化物的水解动力学拆分（HKR）。仅用0.16-0.02 mol％的催化剂（基于催化单元）就可得到高达99％的ee。
