An efficient access to 4-alkylidene-5,6-dihydro-4H-pyrrolo[1,2-c][1,2,3]triazoles

From alkylidenecyclopropanes (MCPs), 4-alkylidene-5,6-dihydro-4H-pyrrolo-[1,2-c][1,2,3]triazoles 6 were prepared in moderate yields through diiodogenation, Cu(I)-catalyzed 1,3-dipolar cycloaddition and subsequent intramolecular Heck reaction.
