Oxidative Povarov Reaction via sp3 C–H Oxidation of N-Benzylanilines Induced by Catalytic Radical Cation Salt: Synthesis of 2,4-Diarylquinoline Derivatives
摘要:
Oxidative Povarov reaction of N-benzylanilines was realized under catalytic radical cation salt induced conditions. The mechanism studies revealed that a radical intermediate was involved in this catalytic oxidation. This method provides a new way to synthesize 2,4-diarylquinoline derivatives.

A one-pot synthesis of quinolines via molecular iodine-catalyzed and air-mediated tandem condensation/imino-Diels–Alder/isomerization/oxidation of simple readily available amines, aldehydes, and alkynes has been developed. This methodology was extended to synthesize quinazolines from two molecules of amines and two molecules of glyoxalates.
