A wide variety of indoloisoquinoline derivatives are prepared from the acid-catalyzed cyclization of 3-amido-2-phenylindoles, which in turn were obtained from the Beckmann rearrangement of 2-phenylindole-3-oximes. (C) 2009 Elsevier Ltd. All rights reserved.

Treatment of 3-amidoindoles with phosphoryl chloride leads to a dimerization of the resulting iminochlorides to form tetrasubstituted imidazoles in moderate yield. One indole ring undergoes ring-opening to allow the formation of the imidazole ring. This strategically simple synthesis considerably expands the scope of delivering N-indolylimidazoles.
