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

Org. Lett. 7th ed., 14 , 1756-1759, (2012)

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.

Ruthenium(0)-catalyzed sp3 C-H bond arylation of benzylic amines using arylboronates.

Org. Lett. 7th ed., 14 , 1930-1933, (2012)

A Ru-catalyzed direct arylation of benzylic sp(3) carbons of acyclic amines with arylboronates is reported. This highly regioselective and efficient transformation can be performed with various combin...

Tandem-type Pd(II)-catalyzed oxidative Heck reaction/intramolecular C-H amidation sequence: a novel route to 4-aryl-2-quinolinones.

Chem. Commun. (Camb.) 36th ed., 48 , 4332-4334, (2012)

A novel catalytic method for synthesizing 4-aryl-2-quinolinones is reported. The process involves two mechanistically independent, sequential Pd(II)-catalyzed reactions--the oxidative Heck reaction an...
