ChemInform Abstract
Phenylchlorocarbene, generated from the phenylchloroazirine (II), reacts with benzofuran (I) to give the cyclopropane derivative (III). On heating, this compound undergoes cleavage of the cyclopropane moiety to afford the benzopyrylium chloride (IV), an unstable intermediate which reacts with aniline (V) to yield the quinoline (VI).
