Bicyclic diols and related derivatives as catalysts for the asymmetric diethylzinc addition to benzaldehyde
摘要:
Chiral bicyclic diols based on bicyclo[2.2.2]octane and bicyclo[2.2.1]heptane have been synthesized and their catalytic capacity in the asymmetric diethylzinc addition to benzaldehyde compared with those described for previously synthesized 2,6-bicyclo[2.2.2]octane-diols (BODOLs). The influence of the number of coordinating sites and the distance between them were studied. (C) 2008 Elsevier Ltd. All rights reserved.

A newclass of chiral non-racemic γ- and δ-amino alcohols based on bicyclo[2.2.1]heptane and bicyclo[2.2.2]octane have been synthesized and used as catalysts in the asymmetric diethylzinc addition to benzaldehyde.
