摘要
Ramirez ylides were synthesized in good yields from Morita-Baylis-Hillman acetates of alpha-bromocin-namaldehyde and phosphines in a one-pot reaction. The Ramirez ylides were formed by a novel intramolecular 1,6-conjugate addition of phosphorus ylide as a key step. (c) 2015 Elsevier Ltd. All rights reserved.
