A novel domino condensation-intramolecular nucleophilic cyclization approach towards annulated thiochromenes

A one-pot protocol towards previously unreported derivatives of thiochromeno [2′,3′:4,5] imidazo[2,1-a]isoquinoline via a domino reaction of isoquinoline-derived iminium salts and α-mercapto benzaldehydes is elaborated. © 2013 Elsevier Ltd. All rights reserved.
