Abstract
The asymmetric epoxidation of allylic cyanohydrins using the Sharpless kinetic resolution (SKR) reaction was explored. The SKR methodology was extended to enals via in-situ conversion into the corresponding cyanohydrin. The prospect of achieving a dynamic Sharpless kinetic resolution was investigated and the enantioselectivity of the SKR of (E)-2-hydroxy-3-methyl-4-phenyl-3-butenenitrile 1 studied. Reversible hydrocyanation of alpha-methyl cinnamaldehyde was developed and a one-pot hydrocyanation/epoxidation process achieved. (C) 2002 Elsevier Science Ltd. All rights reserved.
