Olefin metathesis is now a well-entrenched synthetic technique, and is a powerful method for the clean construction of innumerable classes of chemical architectures. The first example of ring-closing metathesis was reported by dider villemin in 1980 when he synthesized an exaltolide precursor using a wcl/mesn catalyzed metathesis. This mechanism is today considered the actual mechanism taking place in olefin metathesis chauvin's experimental evidence was based on the reaction of cyclopentene.
