The organoaluminum-promoted Claisenrearrangement of allylic vinyl ethers has been mechanistically studied by two sets of experiments and the observed Z and E selectivity is best accounted for by two possible chair-like structures with R substituents axial and equatorial, respectively.
通过两组实验对有机铝促进的烯丙基乙烯基醚的克莱森重排进行了机械研究,观察到的 Z 和 E 选择性最好由两种可能的椅子状结构来解释,其中 R 取代基分别为轴向和赤道。
