nonactivated arenes and amines. This one-pot method utilizes arene-arenophile para-cycloadducts, formed via visible-light-mediated [4+2]-photocycloaddition that undergoes formal allylic substitution with amine nucleophiles under Pd-catalysis. The products are obtained with exclusive syn-1,4-selectivity; the method permits enantioselective desymmetrization of naphthalene, as well as elaborations of amine-containing
在此,我们报告了一种使用简单的非活化芳烃和胺的脱芳香性 Syn-1,4-二胺化方案。这种一锅法利用芳烃-亲芳烃对环加成物,通过可见光介导的 [4+2]-光环加成形成,在 Pd 催化下与胺亲核试剂进行正式烯丙基取代。产品以独特的syn-1,4-选择性获得;该方法允许萘的对映选择性去对称化,以及含胺药物分子的制备。此外,由此产生的不饱和产品适合多种多样化选择。总体而言,这种新颖的脱芳基功能化策略提供了从简单的芳烃中快速、直接地获取复杂的构建块的途径,而这些构建块很难以其他方式制备。
