annulation of enediyne compounds leading to naphthalene frameworks has been developed by using Pd(OAc)2 as the catalyst in the presence of NaI under O2 (1 atm). This reaction provided efficient access to a class of symmetric core‐annulated naphthalenes by the homoannulation of enediyne–imides. Intriguingly, the crossover annulation of enediyne–imides and other functionalized enediynes could also be
通过在O 2(1 atm)的NaI存在下使用Pd(OAc)2作为催化剂,开发了导致萘骨架的烯二炔化合物的第一个双分子氧化环。该反应通过烯二炔-酰亚胺的同环化作用,可以有效地获得一类对称的核环萘。有趣的是,烯二炔-酰亚胺和其他官能化的烯二酮的交叉环合也可以通过相同的催化系统实现,从而导致形成几种不对称的萘衍生物。使用18 O同位素标记和自由基清除剂的初步机理研究表明,自由基氧结合级联反应可能与这种转化有关。
