The development of Rh(III)-catalyzed C–H conjugate addition/cyclization reactions that provide access to synthetically useful fused bi- and tricyclic nitrogen heterocycles is reported. A broad scope of C–H functionalization substrates and electrophilic olefin coupling partners is effective, and depending on the nature of the directing group, cyclic imide, amide, or heteroaromatic products are obtained
据报道,Rh(III) 催化的 C-H 共轭加成/环化反应的发展提供了合成上有用的稠合双环和三环氮杂环。广泛的 C-H 官能化底物和亲电烯烃偶联伙伴是有效的,并且根据导向基团的性质,可以获得环状酰亚胺、酰胺或杂芳族产物。吡咯并菲啶生物碱天然产物氧代阿苏宁的有效合成凸显了该方法的实用性。
