A ‘One Pot’ Synthesis of Acenaphtho[1,2-b]Benzo[f] and Acenaphtho[1,2-b]Benzo[h]Quinolines

Abstract

A short, simple and high yielding ‘one pot’ synthesis of two acenaptho[1,2-b]benzo-quinolines have been described which involved highly regioselective thermal cyclization of enaminoimine hydrochlorides from 2-chloro-1-formylacenaphthylene and ½-naphthylamine.
