A palladium-catalyzed reductive cyclization of nitroarenes has been designed to construct sp3-C-NHAr bonds from sp3-C-H bonds by using an enolizable nucleophile to intercept a nitrosoarene intermediate. Exposure of ortho-substituted nitroarenes to 5 mol ?% of Pd(OAc)2 and 10 mol ?% of phenanthroline under 2 atm of CO constructs partially saturated 5-, 6-, or 7-membered N-heterocycles using α-pyridyl carboxylates, malonates, 1,3-dimethylbarbituric acid, 1,3-diones, or difurans as the nucleophile.

An efficient strategy for the synthesis of a variety of quinolin-2(1 H)-one derivatives has been developed. The reaction proceeded from cinnamide derivatives via a tandem reaction in the presence of NaOH to afford the corresponding 2- quinolin-2(1 H)-one derivatives in good to excellent yields.
