moiety responsible for the activity of acronycine. This oxidation showed the sensitivity of the ethylenic bond, leading to the formation of the corresponding epoxides, diols and/or ketoalcohol. In the case of 5-dimethylamino-2,2-dimethylchromene 8, the double bond was not sensitive to oxidation, but the N-methyl groups reacted to lead to the formamide derivative 16 and an imino-alcohol 17. This methodology
首先研究了仿生催化体系对化学邻域对取代的2,2-二甲基色烯衍生物5-8氧化的影响。然后将其应用于抗癌药物丙烯醛中,以一步法获得由吡喃D环中1,2-双键的反应性产生的氧化产物。这些2,2-二甲基色烯构成负责丙烯醛活性的结构部分。该氧化显示出烯键的敏感性,导致形成相应的环氧化物,二醇和/或酮醇。在5-二甲基氨基-2,2-二甲基色烯8的情况下,双键对氧化不敏感,但N-甲基反应生成甲酰胺衍生物。16和亚氨基醇17。将该方法应用于丙烯醛分子1,使其在制备条件下一步获得两种氧化的化合物,即反式二醇3和酮醇4。
