A highly effective C 1 ‐symmetric gem ‐dimethyl N,P‐ligand has been developed for enantioselective palladium( II )‐catalyzed carbocyclization of 1,6‐enynes, in which the N / C trans mode is established for the first time in the “Mizoroki−Heck‐type” transition state by virtue of the C 1 ‐symmetric N,P‐ligand.
