stereoselective synthetic method for the preparation of multisubstituted 1,3-dienes via an allene–Claisen rearrangement. The Claisen rearrangement of anti-allenyl alcohols provided (1E,3Z)-1,3-dienes, which are essential components of bongkrekic acid, in high stereoselectivities. To demonstrate the synthetic utility of the resulting 1,3-dienes, further functional transformations and Diels–Alder reactions are
我们在此开发了一种立体选择性合成方法,用于通过丙二烯-克莱森重排制备多取代的 1,3-二烯。抗烯醇的 Claisen 重排以高立体选择性提供 (1E,3Z)-1,3-二烯,它们是 bongkrekic 酸的基本成分。为了证明所得 1,3-二烯的合成效用,描述了进一步的功能转化和 Diels-Alder 反应。
