Cu(II)-Catalyzed Allylic Silylation of Morita-Baylis-Hillman Alcohols via Dual Activation of Si-B Bond and Hydroxyl Group.

The reaction of Morita-Baylis-Hillman (MBH) alcohols with Me2PhSiBpin under the catalysis of Cu(OTf)2/pyridine in methanol has been developed. The direct silylation of allylic alcohols via dual activation of the Si-B bond and the hydroxyl group of the MBH alcohol provides an efficient and convenient method for the synthesis of functionalized allylsilanes.
