AbstractA palladium‐catalyzed trans‐hydroalkynylation of N‐sulfonyl ynamides has been achieved for the first time, providing α‐alkynylation adducts in high yields with excellent regio‐ and stereoselectivity. The resulting enyne products can serve as the useful precursors for the elaboration of naphthalene derivatives via a platinum‐catalyzed cycloisomerization reaction.magnified image
