10]-phenanthrolin-7(14H)-ones 29 and 30, and naphtho[1,2-b][1,7]-phenanthrolin-7(14H)-one 31, which were subsequently N-methylated to the desired 14-methylnaphtho[1,2-b][1,10] and [1,7]-phenanthrolinones 6, 7, and 8. Benzo[c]pyrano[3,2-h]acridin-7-one derivatives 3, 16, and 22 displayed cytotoxic activities within the same range of magnitude as acronycine itself, whereas 7-alkoxybenzo[c]pyrano[3,2-h]acridine
1-溴-2-萘甲酸(9)与7-甲氧基-2,2-二甲基-2H-1-苯并吡喃-5-基胺(13)缩合,然后经酸介导的环化反应生成6-甲氧基-3,3 -二甲基-3,14-二氢-7H-苯并[c]吡喃并[3,2-h] ac啶-7-(15),将其进一步甲基化为6-甲氧基-3,3,14-三甲基-3 ,14-二氢-7H-苯并[c]吡喃并[3,2-h] ac啶-7-一(苯并[c]]啶胺)(3)和6,7-二甲氧基-3,3-二甲基-3H-苯并[c]吡喃并[3,2-h] ac啶(4)。四氧化15的氧化得到(+/-)-顺式-二醇16,其在酰化后得到苯并吡喃并and啶和苯并吡喃并one啶酮酯17-22。将9与合适的氨基喹啉23-25缩合得到羧基萘基喹啉胺26-28。环化得到相应的萘并[1,2-b] [1,10]-菲咯啉-7(14H)-29和30,以及萘并[1,2-b] [1,7]-菲咯啉-7(14H) )-31 随后将其N-甲基化为所需的14-甲基萘[1
