A highly selective, controllable and synthetically useful base-promoted intramolecular detosylative cyclization of bis-N-tosylhydrazones has been achieved, affording N-containing heterocycles and cyclic olefins under transition-metal-free or gold-catalyzed procedures, respectively. Moreover, an effective and practical metal-free or gold-catalyzed approach to synthesize polycyclic aromatic compounds is also reported.

Rhodium-catalyzed transannulation of N-sulfonyl-1,2,3-triazoles with vinyl ether has been accomplished for the synthesis of various polysubstituted pyrroles. The present method allows the synthesis of mono-, di-, and trisubstituted pyrroles with appropriate substitutions. Furthermore, the developed methodology was applied in the formal synthesis of neolamellarin A, an antitumor agent.
