Palladium two step: Linear anilides were converted into the title compounds in good to excellent yields through a palladium-catalyzed domino carbopalladation/1,4-palladium shift sequence. The C(sp3)-H activation involves a seven-membered palladacycle, and is chemoselective in the presence of competitive C(sp2)[BOND]H bonds. DMA=N,N-dimethylacetamide, OPiv=pivalate.
