A catalytic method for the selective allylic C–H amination of dienes and trienes using arylhydroxylamines has been developed. This iron-catalyzed approach involves the in situ generation of activated nitrosoarenes, which in turn react with dienes or trienes to give the corresponding aminomethyl dienes or trienes as the major products, and hetero-Diels–Alder adducts as minor products. The selectivity
已经开发了一种使用芳基羟胺对二烯和三烯进行选择性烯丙基 C-H 胺化的催化方法。这种铁催化的方法涉及原位生成活化的亚硝基芳烃,后者又与二烯或三烯反应生成相应的氨甲基二烯或三烯作为主要产物,以及杂-Diels-Alder 加合物作为次要产物。选择性取决于催化剂和底物的结构。我们还研究了使用对位取代的苯基羟胺的取代基效应。
