The syntheses of the title compounds were accomplished via an original sequence of reactions including the ring-closing metathesis of Ï-dienes by using the second-generation Grubbs’ catalyst. The chiral diene precursors are available in racemic or optically enriched form from the corresponding α,α′-disubstituted lactones derivatives
标题化合物的合成通过一系列独特的反应实现,包括使用第二代Grubbs催化剂对ω-二烯进行闭环复分解反应。手性二烯前体可以从相应的α,α′-二取代内酯衍生物中获得,具有外消旋或光学富集形式。
