Highly Selective Nickel-Catalyzed Methyl-Carboxylation of Homopropargylic Alcohols for α-Alkylidene-γ-butyrolactones
摘要:
A first practical Ni(0)-catalyzed highly stereoselective methyl-carboxylation of homopropargylic alcohols with ZnMe2 and CO2 for the efficient synthesis of alpha-alkylidene-gamma-butyrolactones is described. The reaction may be applied to other alkynols.
