Synthesis of 11H-4b,10b-dihydro[1]benzopyrano[4,3-c]isoquinoline-6,11(5H)-diones and 13H-6c,12b-dihydronaphtho[1',2':5,6]-pyrano[4,3-c]isoquinoline-8,13(7H )-dione from homophthalic anhydride and N-(2-hydroxyarylidene)alkylamines

2-Alkyl-3-(2-hydroxyaryl(-3,4-dihydro-1(2H)-isoquinolinone-4-carboxyli c acids (5,13) were prepared from homophthalic anhydride (1) and N-(2-hydroxyarylidene)alkylamines (2,10). The acids 5,13 showed a tendency towards cyclodehydration to give isoquinolin
