摘要

An unprecedented Pd-catalyzed trans-addition of boronic acids to ynamides has been reported, giving alpha,beta-disubstituted enamides in high yields with excellent regio- and stereoselectivity. A possible mechanism involving the palladium carbene intermediate has been proposed to account for the unusual trans-addition.
