Popis: A solid-phase synthesis of benzimidazole N -oxides was developed while attempting to synthesize 1,5-benzodiazepine-2,4-diones. The key step of the synthesis involves the reduction of an arylnitro to a hydroxyamino intermediate which subsequently condenses with an internal carbonyl group to give a benzimidazole N -oxide. A library of nine benzimidazole N -oxides was prepared on SynPhase™ Lanterns using this reduction–cyclization methodology.
