Abstract
An acid-promoted Aubé–Schmidt's rearrangement of arylmethyl azides provides a useful in situ iminium ion intermediate, which can be efficiently trapped by various nucleophiles. We report here the reaction of this iminium ion with aromatic nucleophiles to give N-arylmethyl arenes and the reaction with heteroaromatic compounds to give fused polycyclic heteroaromatic products in a formal [4+ 2] cycloaddition. The short synthesis of ...
