[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.

of acyclic omega chain conjugateddiene analogues of enisoprost were synthesized and evaluated for gastric antisecretory and diarrheagenic activities in comparison to enisoprost and a previously identified cyclic dienyl analogue. Several novel approaches to the cuprate reagents involved in the synthesis of the series are described. From this SAR study, it appears that both the conjugateddiene and
