The Cu (II)-catalyzed addition of two molecules of a 3-aryl-2 H-azirine to diazotetramic or diazotetronic acids proceeds as a domino reaction with the formation of 1, 2, 3-triazole derivatives with ortho-fused (pyrrolo [3, 4-b] pyrrol or furo [3, 4-b] pyrrol) and spiro-cyclic (1- oxa-4, 7-diazaspiro [4.4] nonane or 1, 7-dioxa-4-azaspiro [4.4] nonane) substituents at the N2 position. The disclosed reaction is a new type of formation of a 1, 2, 3-triazole ring from ...
