Regioselective metathesis reactions of various polyunsaturated ketones and alcohols

The reactivity for metathesis reaction of some polyunsaturated cyclopentanols, and of a polyunsaturated ketone bearing vinyl groups or vinyl and propenyl groups has been examined. In the presence of two of these reactants, depending on the ruthenium catalyst employed, either the ring closing metathesis or the cross-coupling metathesis was observed.
