Exclusive Chemoselective Reduction of Imines in the Coexistence of Aldehydes Using AuNPore Catalyst
摘要:
Aldimines ((RHC)-H-1=NR2) were reduced in the coexistence of aldehydes ((RCHO)-C-1) with 100% chemoselectivity by the use of AuNPore giving corresponding amines ((RH2C)-H-1-NHR2) in high chemical yields.

CH Aerobic Oxidation Induced by a Catalytic Radical Cation Salt
An unexpected reaction of cinnamylanilines was achieved through the radical cation salt‐induced aerobic oxidation of sp3 CH bonds, providing a series of 2‐arylquinolines. The mechanistic study shows that the cinnamylaniline was oxidized to an imine, which was attacked by the aniline generated through decomposition of the corresponding imine. After further intramolecular cyclization and aromatization
