Ring Closing Metathesis Reactions of Imidazole Derivatives

Abstract

A series of diene substituted imidazole derivatives has been prepared from the corresponding haloimidazoles via halogen-magnesium exchange and electrophile quench. These derivatives were explored as susbstrates in a ring closing metathesis reaction, which was successful if the imidazolium ion was used. In addition, one successful example of a ring closing metathesis reaction of an enyne derivative was performed, with the resulting diene successfully engaging in a Diels-Alder reaction.
