Bicyclic Dienes

A new class of bicyclic dienes which contain a σ plane of symmetry are efficiently prepared in a diastereoselective fashion using ring closing metathesis reactions. These molecules have potential as starting materials for a wide range of organic targets.Key words: metathesis, catalysis, stereoselective, decalin, desymmetrization.
