摘要：

Silyl epoxides In-e react with lithium diphenylphosphide and then with methyl iodide to give vinylphosphonium iodides resulting from alpha-opening of the epoxide ring and subsequent Peterson elimination. In the same conditions, the E-beta-phenyl-alpha-tert-butyldiphenylsilylepoxide If leads to the corresponding silyl enol ether 5 by beta-opening followed by Brook rearrangement. Both processes are regio-and stereospecific. (C) 1997 Elsevier Science Ltd.
