The reaction of nitrones with pyrroles and furan: an easy access to heteroaromatic hydroxylamines and bis(heteroaryl)alkanes

N-Benzylnitrones react with heteroaromatic compounds such as pyrroles or furan in the presence of hydrogen chloride. Either heteroaromatic N-benzylhydroxylamines, symmetrical or unsymmetrical 2,2′-bis(heteroaryl)alkanes could be selectively produced depending on the experimental conditions.
