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 [4-3c] isoquinoline-8,13 (7H)-dione from homophthalic anhydride and N-(2-hydroxyarylidene) alkylamines

towards cyclodehydration to give isoquinoline derivatives with fused [1] benzopyrane (8) or naphthopyrane (12) ring system. The relative configurations of the novel fused heterocyclic compounds 5,8,12,13 and related compounds were determined by NMR studies, and in the case of 13 also by means of X-ray analysis. Some MM2 force field molecular mechanics calculations on some selected fused heterocycles were
由高邻苯二甲酸酐(1)和N-(2-羟基亚芳基)制备2-烷基-3-(2-羟基芳基)-3,4-二氢-1(2H)-异喹啉酮-4-羧酸(5,13)烷基胺(2,10)。酸5,13表现出环脱水的趋势,以生成具有稠合的[1]苯并吡喃(8)或萘并吡喃(12)环系统的异喹啉衍生物。通过NMR研究确定了新颖的稠合杂环化合物5、8、12、13和相关化合物的相对构型,并且在13的情况下也通过X射线分析来确定。在某些选定的稠合杂环上进行了一些MM2力场分子力学计算。迄今为止,尚未报道内酯12中并入的萘并[1',2':5,6]吡喃并[4,3c]-异喹啉环系统。
