Macarpine (1), a 2, 3, 7, 8, 10, 12-hexaoxygenated benzo[c]phenanthridine alkaloid (O-6 base), was effectively synthesized from sesamol methyl ether (7) through the newly developed aromatic nitrosation under basic condition. The tests for the cytotoxicity of 1 and its analogous 2, 3, 7, 8, 10-pentaoxygenated (O-5) bases 23, 24 against HeLa S3 tumor cell showed that 1 exhibited the highest activity among them.
