Visible-Light-Induced C (sp3)–H Functionalization of Tosylhydrazones: Synthesis of Polysubstituted Pyrroles under Metal-Free Conditions
摘要:
Iodine catalyzed C (sp(3))-H functionalization of tosylhydrazones with beta-enamino esters under visible light irradiation for the synthesis of trisubstituted pyrroles has been described. The present method is also applicable to a alpha-substituted tosylhydrazones to yield the tetra-substituted pyrroles.
