  Sila-Morita−Baylis−Hillman Reaction of Arylvinyl Ketones: Overcoming the Dimerization Problem

  摘要：

  Arylvinyl ketones, under Morita-Baylis-Hillman (MBH) reaction conditions, produce a mixture of dimerization products. We propose a solution to this problem: a sila-MBH reaction. This cascade reaction involves addition of phosphine catalyst to arylvinyl ketones, trapping of the forming beta-sllylenolate with aldehyde, followed by a 1,3-Brook rearrangement to give the Si-MBH adducts in good to excellent yields.
