ABSTRACT A novel iron-catalyzed oxidative coupling of indoles with α-amino carbonyl compounds has been developed. The transformation provides an attractive approach to the synthesis of 3-acylindoles, with the advantages of easily available starting materials and high functional group tolerance. Furthermore, control experiments imply that a radical process maybe involved in this reaction. GRAPHICAL

selective C–N bond oxidative cleavage method to 3-acylated indoles by Pd-catalyzed oxidative cross coupling of indoles with α-aminocarbonylcompounds has been developed; moreover, one-pot synthesis of 3-acylated indoles from 2-ethynylanilines and α-aminocarbonylcompounds has also been established. Importantly, the products 3-acylated indoles can be used to construct polyheterocyclic compound, which can
