metal‐catalyzed addition reaction of 1,3‐diketones to ynamides, which provides access to unprecedented alkoxy‐substituted enamides, is disclosed herein. A screening of catalytic systems showed that both a phosphapalladacycle and a cationic gold complex were capable of promoting this reaction rapidly and cleanly. The scope investigation revealed that variously substituted terminal ynamides and cyclic 1
