A Cp*RhIII-catalyzed oxidative annulation of β-enaminonitriles with alkynes was reported to achieve selective synthesis of polysubstituted 1-naphthylamines and naphtho[1,8-bc]pyridines via multiple C–H activations. Assisted by a naphthylamine NH2 group, 1-naphthylamines were also readily cyclized to produce naphtho[1,8-bc]pyridines. In addition, the obtained naphtho[1,8-bc]pyridine derivatives exhibit
据报道,Cp * Rh III催化的炔烃对β-烯腈的氧化环化反应通过多种C-H活化选择性地合成了多取代的1-萘胺和萘[1,8- bc ]吡啶。在萘胺NH 2基团的辅助下,1-萘胺也很容易被环化以生成萘[1,8- bc ]吡啶。此外,所获得的萘并[1,8- bc ]吡啶衍生物在固态下表现出强烈的荧光。
