Cationic Pd(II)-catalyzed highly enantioselective arylative cyclization of alkyne-tethered enals or enones initiated by carbopalladation of alkynes with arylboronic acids.

Cationic Pd(II)-catalyzed enantioselective arylative cyclization of alkyne-tethered enals or enones initiated by carbopalladation of alkynes was developed without the necessity of a redox system.
