摘要

A metal- and oxidant-free procedure for the three-component haloazidation/cyclization of phenyl-linked 1,6-enynes with TMSN3 and N-iodo(bromo)succinimide under the irradiation of visible light was described. Moreover, this reaction involved a radical addition/5-exo-dig cyclization/radical coupling process, and realized simultaneous construction of C-N, C-C, and C-X (I, Br) bonds in one step.
