Since the strategy for the synthesis of 9-, 10- and 11-nitronoracronycine [3,4] could not be applied to the 8-nitronoracronycine 9, we here report the preparation of the latter by a fusion of methyl 2-amino-6-nitrobenzoate 2 and phloroglucinol 3. The fusion of 2 and 3 gave 1,3-dihydroxy-8-nitro-9(10H)-acridinone 6. Subsequent methylation, demethylation and reaction with 2-chloro-2-methyl-3-butyne afforded
由于合成9-,10-和11-硝基降雪松碱[3,4]的策略不能应用于8-硝基降雪松碱9,我们在这里报告了通过将2-氨基-6甲基甲基融合而制备后者的方法。 -硝基苯甲酸酯2和间苯三酚3。2和3的融合得到1,3-二羟基-8-硝基-9(10 H)-ac啶酮6。随后的甲基化,脱甲基和与2-氯-2-甲基-3-丁炔反应,得到所需的8-硝基降冰片碱9。化合物9,1,3-二甲氧基-10-甲基-8-硝基9(10 ħ) -吖啶酮7和1,3-二羟基-10-甲基-8-硝基9(10美国国家癌症研究所(NCI)测试了H)-ac啶酮8的可能抗癌活性。
