The Photochemical Cyclodehydrogenation Route to Polycyclic Azaarenes

Abstract

This paper reports an investigation of photochemical cyclodehydrogenation for the preparation of polycyclic azaarenes. Various naphthoquinolines and naphthoisoquinolines were obtained from 2-, 3-, and 4-[2-(1- and 2-naphthyl)vinyl]pyridine. 4-[2-(3-Phenanthryl)vinyl]pyridine gave pyreno[1,10-hij]isoquinoline. An efficient preparation of (2-arylvinyl)pyridines is described.
