Directed by the strategy of C–H activation relay (CHAR), an efficient construction of isatin skeleton was developed through catalytic oxidation of glycineesters. The mechanistic study reveals that the oxidation of the relatively active C–H bonds initiated the followed activation of remote and inert C–H bonds, and an intramolecular 1,6-hydrogen shift was involved as a key step.

Directed by the strategy of C–H activation, an efficient construction of the isatin skeleton was developed through aerobic oxidation of glycine esters. The reactions were performed under CF3COOH/O2 conditions in the absence of metal catalysts. The reaction mechanisms were investigated with control experiments.
