Article abstract of DOI:10.1016/S0040-4039(97)01060-5

Anhydrous indium trichloride (InCl₃) is found to catalyze the imino Diels-Alder reactions and results in facile synthesis of quinoline derivatives A previously unreported series of phenanthridinones was obtained by the treatment of cyclohexenon
