The combined carbometalation reaction of ynol ethers followed by a zinc homologation and further allylation reactions lead to an efficient preparation of allylic vicinal diols. The stereochemical outcome of the reaction shows that the substituent of the aldehyde occupies a pseudoaxial position in a Zimmerman-Traxler transition state.
醇醚的交叉羰基化反应，随后进行锌同系化和进一步的烯丙基化反应，可有效地制备烯丙基邻二醇。反应的立体化学结果表明，醛的取代基在 Zimmerman-Traxler 过渡态中占据假轴向位置。
