applicable Ru‐catalyzed protocol for Z‐selective ring‐opening/cross‐metathesis (ROCM) is disclosed. In addition to reactions relating to terminal alkenes of different sizes, the first examples of Z‐selective ROCM processes involving heteroaryl olefins, 1,3‐dienes, and O‐ and S‐substituted alkenes as well as allylic and homoallylic alcohols are reported. Z‐Selective transformations with an α‐substituted
公开了适用于Z选择性开环/交叉复分解(ROCM)的广泛适用的Ru催化方案。除了与不同大小的末端烯烃有关的反应外,还报道了Z选择性ROCM方法的第一个实例,该方法涉及杂芳基烯烃,1,3-二烯,O和S取代的烯烃以及烯丙基和均烯丙基醇。用α-取代的烯丙醇进行的Z选择性转化显示拥挤的Z高非对映选择性的烯烃。可以在2.0–5.0 mol%的最近公开的Ru基二硫醇盐络合物的存在下进行转化,该络合物可轻松地从市售原料中一步制备。通常,转换会在环境温度下进行,并会在八小时内完成;以高达97%的收率,> 98:2 Z / E和> 98:2非对映异构体比获得产物。本研究揭示了钌基二硫醇盐在机械上的重要属性,该属性是由于与阴离子S基配体的静电相互作用而产生的。
