摘要：

Anhydrous indium trichloride (InCl3) is found to catalyze the imino Diels-Alder reaction of 3,4-dihydro-2H-pyran and indene with Schiff's bases to afford pyrano[3,2-c]quinolines and indeno[2,1-c] quinolines. Imino Diels-Alder reactions of N-benzylidene 1-naphthylamine with 3,4-dihydro-2H-pyran and indene results in efficient synthesis of phenanthridine derivatives. (C) 1998 Elsevier Science Ltd.
