Application
β-Amination of Aliphatic Amides via the β-C(sp3)―H Bonds Activation
Typical Procedure:
Substrate (0.1 mmol), [Pd(allyl)Cl]2 (1.8 mg, 0.005 mmol), tris[3,5-bis(trifluoromethyl)phenyl]phosphine (13.4 mg, 0.02 mmol), O-benzoyl hydroxylamine (0.4 mmol), 4Å molecular sieves (50 mg), and Cs2CO3 (130 mg, 0.4 mmol) are weighed in air and placed in a Schlenk tube (50 mL) with a magnetic stir bar. The reaction vessel is evacuated and backfilled with nitrogen (×3), and DCM (1.5 mL) is added afterwards. The reaction mixture is heated to 120 °C for 16 hours under vigorous stirring. Upon completion, the reaction mixture is cooled to room temperature. The solvents are removed under reduced pressure and the resulting mixture is purified by a silica gel-packed flash chromatography column using hexane/EtOAc/DCM mixtures as the eluent.
