An auto-oxidation promoted sp3 C–H arylation reaction between N-aryl glycine derivatives and electron-rich arenes, leading to the formation of N-aryl α-aryl α-amino acid derivatives, is described. This atom-economical and environmentally benign reaction proceeds smoothly under mild reaction conditions and requires only Brønstedacid and oxygen (balloon). A plausible radical involved mechanism is proposed

structure formation. A Cu(II)/DDQ/O2 system-catalyzed DOD [4 + 2]-annulation/oxidative aromatization tandem reaction of readily available glycine derivatives and alkylbenzenes was established. This approach facilitates rapid access to a broad scope of substituted quinoline-2-carboxylate derivatives, an important motif in drug discovery. The reaction could feasibly be applied to a 10 gram-scale synthesis

A copper‐catalyzed aerobic oxidative dehydrogenative reaction of glycine derivatives with α′‐angelicalactone is achieved under mild and simple reaction conditions. This strategy can be applicable to a wide range of gylcine esters, including complex substrates derived from (+)‐dehydroisoandrosterone or menthol, thus enabling the oxidative dehydrogenative ring‐opening reaction for producing diverse functionalized
