In this paper, a Cu(II)/Ag(I)-catalyzed cascade reaction of anthranils with sulfonylhydrazone to construct 2-phenyl-3-sulfonyl disubstituted quinolinederivatives under mild conditions was studied. The mechanism study indicated that this reaction involves radical addition, and new C–C, C–N, and C–S bonds were constructed in one step.

electrochemical protocol for the synthesis of 2,3-disubstituted quinolines by reacting benzoxazinones with arylsulfonyl hydrazides was established under simple and mild conditions (room temperature and an undivided cell). The methodology does not require noble catalysts or external oxidants, providing a green and mild pathway for de novo synthesis of functional quinolines with excellent regioselectivity
