Abstract
Herein, a copper‐catalyzed photoinduced [3+3] cycloaddition reaction of α‐acidic isocyanides with 2,5‐diaryltetrazoles is described. The reaction proceeded smoothly with high regioselectivity, affording a range of important 1,2,4‐triazines under mild conditions. The obtained 1,2,4‐triazines were converted into triazine alcohol, Weinreb amide and triazinone easily, which further illustrate the utility of this [3+3] cycloaddition process. [ABSTRACT FROM AUTHOR]
