Several di- and trisubstituted primary (E)-allylic alcohols have been prepared from the corresponding terminal olefins in a highly stereoselective manner (>20:1 E/Z) by sequencing olefin cross-metathesis (CM) with hydride reduction (DIBAL-H) in good yields utilizing only commercially available reagents in a one-pot fashion. The method is a reliable alternative to the direct CM of terminal olefins with
通过以氢化物还原法对烯烃交叉复分解(CM)进行测序(DIBAL-H),从相应的末端烯烃以高度立体选择性的方式(> 20:1 E / Z)制备了几种二和三取代的伯(E)烯丙基醇。)仅使用一锅法仅使用市售试剂即可获得高收率)。该方法是端烯与烯丙醇直接CM的可靠替代方法,后者并不总是立体选择性的,而是高度依赖底物的。
