Herein, the [2 + 2] photocycloaddition between two molecules of (E)-2-(3,4-dimethoxystyryl)-quinoxaline (1) in an acetonitrile solution to form only one cyclobutane isomer out of eleven possible isomers is described. The observed photocycloaddition r

Regiospecific C–N photocyclization of mono- and bis-styryl-substituted N-heterocycles was investigated. We demonstrated that the C–N regiospecificity of the photoinduced electrocyclization is a general feature of ortho-styryl-substituted N-hetero
