developed the first nickel-catalyzed regio-, (E)-stereo- and linear-selective ring-opening/cross-coupling reaction of vinylaziridines with organoboronic acids under mild conditions to construct various skipped aminodienes. The reaction exhibits wide functional-group compatibility, and could be adapted for the introduction of skipped aminodiene functionality into bioactive molecules. In addition, the reaction
跳过二烯非常重要,但由于两种烯烃之间存在 sp 3杂化碳,其合成仍然具有挑战性。在此,我们开发了第一个镍催化的乙烯基氮丙啶与有机硼酸在温和条件下的区域、( E )-立体和线性选择性开环/交叉偶联反应,以构建各种跳跃氨基二烯。该反应表现出广泛的官能团兼容性,并且可以适用于将跳过的氨基二烯官能团引入生物活性分子中。此外,该反应可以在克级规模上进行,以高产率和线性选择性(90%产率,l:b>20:1)提供开环产物。此外,DFT 计算和机制实验提供了对该机制的详细见解。
