rhodium-catalyzed remote C(sp3 )-H borylation of silyl enol ethers (SEEs, E/Z mixtures) by alkene isomerization and hydroboration is reported. The reaction exhibits mild reaction conditions and excellent functional-group tolerance. This method is compatible with an array of SEEs, including linear and branched SEEs derived from aldehydes and ketones, and provides direct access to a broad range of structurally
报道了通过烯烃异构化和硼氢化反应的铑催化的甲硅烷基烯醇醚(SEEs,E / Z混合物)的远程C(sp3)-H硼化。该反应表现出温和的反应条件和优异的官能团耐受性。该方法与一系列SEE兼容,包括衍生自醛和酮的直链和支链SEE,并且可以以优异的区域选择性和高收率直接获得各种结构多样的1,n-硼醚。这些化合物是各种有价值的化学品(例如1,n-二醇和氨基醇)的前体。
