Reductive acid-catalyzed rearrangement of 3-(2-nitrobenzyl)quinoxalin-2(1Н)-ones in the presence of Na2S2O4 – effective method for the synthesis of 2-(indol-2-yl)benzimidazoles

[Figure not available: see fulltext.] An effective one-step method is proposed for the synthesis of 2-(indol-2-yl)benzimidazoles from 3-(2-nitrobenzyl)quinoxalin-2(1Н)-ones without using metal catalysts and reagents. This method is based on the Mamedov rearrangement of 3-(2-aminobenzyl)quinoxalin-2(1Н)-ones, formed in situ by the action of Na2S2O4, giving 2-(indol-2-yl)benzimidazoles as the products.
