Dipolarophilic behavior of the isoxazole ring in intramolecular nitrilimine cycloadditions

Upon base treatment with silver carbonate, isoxazolyl-substituted hydrazonoyl chlorides (4) and (12) undergo a sequential intra- intermolecular nitrilimine cycloaddition giving tetracyclic pyrazolydine derivatives (7) and (15).
