InCl3-catalyzed intramolecular carbonyl-olefin metathesis

Abstract

An efficient and novel synthetic strategy for the generation of different carbocyclic moieties by ring closing carbonyl-olefin metathesis is reported. Herein, we describe a sustainably attractive protocol for one of the most powerful carbon-carbon bond-forming reactions, based on solvent-reduction, use of InCl₃ catalyst, and microwave irradiation, affording target compounds with yields up to 96%.
