✦ Synopsis

The preparation of a number of dienylimidazole via chemoselective metal-halogen exchange and their utility in ring-closing metathesis is described. Essentially all regioisomeric permutations participate in metathesis with the notable exception of 4-vinyl-5-allylimidazoles, provided that the imidazole N3 atom is protonated.

Ring-closing metathesis (RCM) was used to synthesise five 4H-chromenes, a naphthol and an indenol. These are the first examples of RCM applied to the synthesis of such benzo-fused bicyclic compounds.
