A highly effective C1-symmetric gem-dimethyl N,P-ligand has been developed for enantioselective palladium(II)-catalyzed carbocyclization of 1,6-enynes, in which the N/Ctrans mode is established for the first time in the “Mizoroki−Heck-type” transition state by virtue of the C1-symmetric N,P-ligand.
