摘要

Abstract A one-pot procedure for the conversion of aromatic and heteroaromatic 2- nitroamines into bicyclic 2H-benzimidazoles is described. The procedure employs formic acid, iron powder, and an additive such as NH 4 Cl to reduce the nitro group and effect the imidazole cyclization with high-yielding conversions generally within one to two hours. The compatibility with a wide range of functionality demonstrates the general utility of this ...
