o-nitrophenols, the resulting adducts can be deallylated by a palladium-catalyzed process leading to a formal Ugi−Smiles coupling with ammonia. This new sequence, combined with hydrogenolysis of the nitrogroup, offers an interesting multicomponent entry to benzotriazole and benzimidazole scaffolds.
