Nickel-catalyzed highly regioselective multicomponent coupling of ynamides, aldehydes, and silane: A new access to functionalized enamides

A new method for preparation of functionalized enamides by a nickel-catalyzed multicomponent coupling of ynamides, aldehydes, and silane has been developed. The coupling reaction proceeded in the presence of a nickel-IMes catalyst to give the corresponding gamma-silyloxyenamide derivative, which has an allylic alcohol moiety in the molecule, in a highly stereoselective manner.
