Salts of 2,3,8,9-tetrasubstituted alkoxy-, hydroxy-, and acetoxybenzo(c)phenanthridines as well as the corresponding 6-methoxy-5,6-dihydrobenzo(c)phenanthridines were prepared from appropriate chalcones through the tetralone and the 4b,10b,11,12-tetrahydrobenzo(c)phenanthridine intermediates. Complete O-demethylation of the tetramethoxybenzophenanthridine was achieved by fusion with pyridine hydrochloride
由适当的查耳酮通过四氢萘酮和四氢萘酮制备2,3,8,9-四取代的烷氧基,羟基和乙酰氧基苯并(c)菲啶的盐以及相应的6-甲氧基-5,6-二氢苯并(c)菲啶的盐。 4b,10b,11,12-四氢苯并(c)菲啶中间体。通过在高温下与吡啶盐酸盐熔融,实现了四甲氧基苯并菲的完全O-去甲基化。标题化合物具有抗小鼠白血病L1210和P388的活性,某些化合物可抗Lewis肺癌。讨论了环境性质关于这些化合物的氮原子和取代基的重要性。3,4-二甲氧基-3,4-亚甲二氧基查尔酮具有抗白血病P388的活性。
