Lewis Acid Catalyzed Benzylic C-H Bond Functionalization of Azaarenes: Addition to Enones

[摘要]：A Lewis acid catalyzed benzylic C-H bond functionalization of alkyl-substituted azaarenes is described. Sc(OTf)(3) and Y(OTf)(3) promoted the direct addition of alkyl-substituted azaarenes and benzoxazole to enones and an alpha,beta-unsaturated N-acylpyrrole. Products were obtained in 60-96% yield.
