An oxidative cross-coupling reaction between activated olefins and vinyl boronate derivatives has been developed for the highly stereoselective construction of synthetically useful (E,E)-1,3-dienes. The highlight of this reaction is that exclusive stereoselectivity (only E,E-isomer) was achieved from a base-free, ligand-free, and mild catalytic condition with a less expensive [RuCl2(p-cymene)]2 catalyst
已经开发出活化烯烃和乙烯基硼酸酯衍生物之间的氧化交叉偶联反应,以用于合成有用的(E,E)-1,3-二烯的高度立体选择性的结构。该反应的亮点在于,使用便宜的[RuCl 2(p- Cymene)] 2催化剂,可从无碱,无配体和温和的催化条件下获得独特的立体选择性(仅E,E-异构体)。
