palladium(0)-catalyzed, Cu(I)-mediated synthetic route to trisubstituted olefins and conjugate dienes has been developed via oxo directing Liebeskind–Srogl cross-coupling reactions of gem-dihaloolefin-type α-oxo ketene dithioacetals with aryl and alkenylboronic acids. The synthetic protocol has demonstrated rare examples of transition-metal-promoted transformations of ketene dithioacetals, providing a novel route to
一种有效的钯(0)催化,铜(I)介导的合成路线,以三取代的烯烃和共轭二烯已开发经由氧代引导利贝斯金德-Srogl交叉偶联反应的宝石-dihaloolefin型α氧代烯酮二硫与芳基和烯基硼酸。合成方案已证明了过渡金属促进的乙烯酮二硫缩醛转化的罕见实例,为高功能化的共轭二烯提供了一条新颖的途径。
