Heterocyclic Synthesis Using Nitrilimines: Part 5.Synthesis of Some Novel Spiro Heterocycles

摘要

A new class of spiro-triazoles (4a-m) were synthesized from the reaction of corresponding nitrilimines 2 with substituted heterocyclic benzoylhydrazones 3 in good yields.The spectral data of the new synthesized compounds are in full agreement with their molecular structure.
