Efficient Construction

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.
