Abstract

Abstract The Bischler-Napieralski dihydroisoquinoline synthesis was proven to occur via imidoyl chlorides and the corresponding nitrilium salt. The two-step process required much milder conditions (20–50) compared to drastic classical conditions of refluxing at 100–200. The Bischler-Napieralski reaction is shown to share a common intermediate with two other well-known reactions: the von Braun and the Ritter reactions.
