using ruthenium-catalyzed olefin cross-metathesis of 1-propenyl pinacol boronate and various alkenes, including functionalized and 1,1-disubstituted alkenes. The resultant boronate cross products are stereoselectively transformed into predominantly Z-vinyl bromides and E-vinyl iodides. The vinyl bromides may be synthesized in a two-step, one-pot synthesis from a variety of olefins, resulting in a Z-selective
适用于铃木交叉偶联反应的功能化乙烯基频哪醇硼酸酯是使用1-丙烯基频哪醇硼酸酯和各种烯烃(包括功能化和1,1-二取代的烯烃)经钌催化的烯烃交叉复分解合成的。将所得的硼酸酯交叉产物立体选择性地转化为主要的Z-乙烯基溴化物和E-乙烯基碘化物。乙烯基溴化物可以由多种烯烃以两步,一锅法合成来合成,从而导致Z选择性形式的乙烯基溴化物交叉复分解反应。
