Few methods allow for the direct conversion of cycloalkenes into cycloalkadienes with high chemo‐ and regioselectivity. Herein, we report a convenient one‐pot process for this transformation that involves the unprecedented N‐preferential group transfer of N‐oxoammonium salts to cycloalkenes, followed by Cope elimination, to afford cycloalkadienes at room temperature and pressure.
很少有方法能够将环烯烃直接转化为具有高化学和区域选择性的环烷二烯。在此,我们提出一个方便的一锅法用于该转化,其涉及的前所未有的N-优先基团转移Ñ -oxoammonium盐环烯烃,随后柯普消除,以得到在室温和压力环二烯。
