developed. This process features readily available starting materials and mild reaction conditions. Further transformations of the obtained dibranched 1,3-dienes, through Diels-Alder reactions and indene synthesis, are also demonstrated, which reveal their great potential for synthetic utility.
已经开发了一种容易且高度区域选择性的N-甲苯磺酰P的Pd催化氧化偶联,可提供对2,3-二取代-1,3-丁二烯的有效利用。该方法具有容易获得的起始原料和温和的反应条件的特征。还证明了通过Diels-Alder反应和茚合成对所获得的二支化的1,3-二烯的进一步转化,这表明它们具有巨大的合成用途潜力。
