unsubstituted cyclopentadienyl rhodium(III) (CpRh III ) complex is a highly active catalyst for the aerobic oxidative ortho C-H bond olefination of sterically demanding ortho -substituted benzamides with alkenes. This catalysis was successfully applied to the diastereoselective synthesis of axially chiral N , N- dialkylbenzamides. The combination of the ruthenium(II)-catalyzed enantioselective hydrogenation
