Article Abstract

Iodine catalyzed C (sp)-H functionalization of tosylhydrazones with β-enamino esters under visible light irradiation for the synthesis of trisubstituted pyrroles has been described. The present method is also applicable to α- substituted tosylhydrazones to yield the tetra-substituted pyrroles.
