Acid Catalyzed Multicomponent Reaction to Access Functionalized N‐Benzhydryl Amides: A Tandem Ritter Reaction

  • Organic Chemistry
  • Physical and Theoretical Chemistry

AbstractAcid catalyzed multicomponent reaction (MCR) for the synthesis of N‐benzhydryl amide derivatives from aldehydes, N,N‐disubstituted arylamines and nitriles is reported. The reaction is compatible with electronically differentiating aryl/heteroaryl aldehydes/acetals, different nucleophiles (cyclic and acyclic N,N‐disubstituted arylamines,β‐naphthols, 1,3 dicarbonyl, 1,3,5‐trimethoxy benzene), alkyl nitriles, aryl/heteroaryl nitriles in catalytic TFA/TfOH through tandem Ritter reaction. The one‐pot MCR with broad substrate scope generated a wide variety of sterically hindered N‐substituted amides and is successfully applied for the synthesis of isoindolinone.
