aerobic oxidation of alkyl 4‐anilinocrotonates is described. In the presence of dioxygen, sp3 C−H bonds in 4‐anilinocrotonates can easily be oxidized by using a catalytic amount of a radicalcationsalt, providing a radical intermediate. After further oxidation and domino cyclization, the desired quinoline derivatives were afforded in high yields. This reaction provides a new way to construct the pharmaceutically
