Intramolecular Diels-Alder furan-mediated synthesis of 8-aryl-3, 4-di-hydroisoquinolin-1(2H)-ones, convenient precursors of indeno[1,2,3-ij]isoquinolines

We describe herein preliminary studies on the Intramolecular Diels-Alder Furan-Mediated Synthesis of 8-Aryl-3, 4-di-hydroisoquinolin-1(2H)-ones that constitutes a new, formal synthesis of Indeno[1,2,3-ij]isoquinolines.
