A new approach to the synthesis of chiral vinyl carbinols from 2,3-epoxy alcohols
摘要:
The regioselective opening with benzoic acid of 2,3-epoxy alcohols obtained from the asymmetric epoxidation of 2,3-allylic alcohols, and deoxygenation of the resulting diol benzoates provides an effective, general and simple method to convert chiral 2,3-epoxy alcohols, into vinyl carbinols without the loss of any optical purity.
