Intramolecular oxidative cyclization of alkenes by rhodium/cobalt porphyrins in water

Abstract

Intramolecular oxidative cyclization of alkenes provides a unique pathway to obtain unsaturated heterocyclic compounds. The rhodium(III)/cobalt(III) tetra(p-sulfonatophenyl)porphyrin ((TSPP)M^III) in water was observed to mediate the intramolecular oxidative functionalization of alkenes to a series of unsaturated oxygen heterocyclic compounds.
