Abstract:

A redox-neutral avenue to access isoquinolines has been realized by a Co(III)-catalyzed C-H activation process. Starting from readily available N-sulfinyl imine substrates and alkynes, the reaction occurred via N-S cleavage with broad substrate scope and functional group compatibility in the presence of cost-effective cobalt catalysts.

Key words: Cobalt(III) catalyst, Carbon-hydrogen activation, N-sulfinyl imine, Isoquinoline
