A novel cascade Kröhnke condensation-an intramolecular nucleophilic cyclization approach toward annulated chromenes

A one-pot protocol toward previously unreported derivatives of chromeno[2′,2′:4,5]imidazo[2,1-a]isoquinoline via a cascade reaction of isoquinoline-derived immonium salts and α-hydroxy aromatic aldehydes is elaborated. © 2010 Elsevier Ltd. All rights reserved.
