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
The reaction of indole and β-carbonyl nitrile to generate dicarbonyl indoles has been developed. This process involves α-oxonation of the β-carbonyl nitrile, Friedel–Crafts reaction with indoles and retro-cyanohydrination form dicarbonyl indoles.

indoles selectively furnishes 1 and 2 with the aid of tert‐butyl hydroperoxide (TBHP). The method represents the first example of a copper‐catalyzedα arylation of α‐amino carbonyl substrates leading to α‐aryl α‐imino and α‐aryl α‐oxo carbonyl compounds using a CH oxidation strategy.
