Twofold Brook rearrangement-mediated tandem reactions of δ-silyl-γ,δ-epoxy-α,β-unsaturated acylsilanes with a cyanide ion
摘要:
Reaction of delta-silyl-gamma,delta-epoxy-alpha,beta-unsaturated acylsilanes with KCN in the presence of chloro or cyanoformates gives highly functionalized dienol silyl ether derivatives via a twofold Brook rearrangement-induced tandem sequence. (C) 2004 Elsevier Ltd. All rights reserved.
