Hydrogen bond assisted ortho-selective C(sp2)–Hamination of nitrosoarenes and subsequent α-C(sp3)-H functionalization of aliphatic amines is achieved under metal-free conditions. The annulation of nitrosoarenes and 2-hydroxy-C-nitroso compounds with N-heterocycles provides a facile excess to a wide range of biologically relevant ring-fused benzimidazoles and structurally novel polycyclic imidazoles
氢键辅助的亚硝基芳烃的邻位选择性C(sp 2)-H氨基化和随后的α-C(sp 3)-H脂肪族胺的官能化在无金属条件下实现。亚硝基芳烃和2-羟基-C-亚硝基化合物与N-杂环的环化分别提供了相对于广泛的生物学相关的环稠合的苯并咪唑和结构上新颖的多环咪唑的简便过量。发现在卤代亚硝基芳烃的C(sp 2)–H胺化过程中,亲核芳香族氢取代(S N ArH)比经典S N Ar反应更可取。
