Divergent access to bicyclo[3.1.0]hexane and cyclopenta[c]pyrazole scaffolds bearing azole azine units has been developed. The approach involves intramolecular cyclization of 5-iodo-1,2,3-triazoles acting as stable diazoimine precursors with concomitant noncatalytic (3 + 2)-cycloaddition. choice solvent allows control the outcome cascade transformation. developed procedure is simple cost-efficient allowed important heterocycles be obtained in one-pot various functional groups.
