Iodine catalyzed C (sp3)-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 tosyl
THERMAL REARRANGEMENT OF 3H-PYRROLES BY COMPETITIVE -SIGMATROPIC SHIFTS, AND THE REVERSIBILITY OF THE 3H- TO 2H-PYRROLE INTERCONVERSION

3-Ethoxycarbonyl-3H-pyrroles are converted via thermal -ester shifts to the isomeric 1H-pyrrole-4- and N-esters.Isolable intermediate 2H-pyrroles are converted into the same products, and also into the 3H-pyroles, demonstrating conclusively the reversibility of the 3H- to 2H-pyrrole interconversion.
