Construction of quinoline-fused lactones and 2,3-disubstituted quinolines via catalytic aerobic sp3 C–H oxidation: application of fragment-reassembly strategy.

Designed by fragment-reassembly strategy, the reaction between glycine esters and cyclic enol ethers was achieved in the catalysis of TBPA +· /O 2 , yielding a series of quinoline-fused lactones and 2,3-disubstituted quinolines. This approach provided an efficient method to construct quinoline skeleton, in which two new rings and two new C–C bonds were built in one pot. [ABSTRACT FROM AUTHOR]
