This letter shows the highly stereoselective synthesis of substituted (E)-1,3-dienes from substituted propargylic diols via the double ortho ester Claisen rearrangement. The cyclohexyl-substituted diene undergoes thermal Diels–Alder cycloaddition with maleic anhydride to produce the corresponding bicyclic diester in highly stereoselective manner.
这封信显示了通过双原酸酯克莱森重排从取代的炔丙二醇中高度立体选择性地合成了取代的(E)-1,3-二烯。环己基取代的二烯与马来酸酐进行热Diels-Alder环加成反应,以高度立体选择性的方式生成相应的双环二酯。
