[Reaction: see text] Various substituted conjugateddienes have been made by olefin cross-metathesis. Using either electronic or steric "protection," one of the olefins of the conjugateddiene was deactivated relative to the other for cross-metathesis. The reactions proceed with very high chemoselectivity and, when steric deactivation is used, very high diastereoselectivity.
