Synthesis of thiepin-annulated pyrone and coumarin heterocycles by Grubbs' second generation catalyst mediated enyne metathesis
Synthesis of thiepin-annulated pyrone and coumarin derivatives has been achieved by the ring-closing enyne metathesis using the second generation Grubbs' catalyst under a nitrogen atmosphere.
