convenient synthesis of carbazole-1,4-quinone alkaloid koeniginequinones A and B using a tandem ring-closing metathesis with the dehydrogenation reaction sequence under an O2 atmosphere as an important step. Using this method, carbazole-1,4-quinones substituted at the 5-, 6-, 7-, and/or 8-positions have been synthesized. Moreover, 24 compounds, including koeniginequinones A and B, have been evaluated for
我们报告了在O 2气氛下使用串联脱氧反应序列的串联闭环复分解法方便地合成咔唑1,4-醌生物碱甲酮醌A和B的重要步骤。使用这种方法,已经合成了在5-,6-,7-和/或8-位取代的咔唑-1,4-醌。此外,已经评估了24种化合物(包括甲烯乙醌A和B)对HCT-116和HL-60细胞的抗增殖活性,而6-硝基类似物对两种肿瘤细胞均表现出最有效的活性。
