An improved synthesis of 3-(substituted)pyrimido[4,5-c]pyridazine-5,7(1H,6H)-diones, a known subclass of 4-deazatoxoflavins, is reported. The approach involves treatment of 3-methyl-6-(1-methylhydrazinyl)uracil with representative phenyl and alkyl glyoxal monohydrates, which in turn are obtained by selenium dioxide oxidation of the corresponding phenyl and alkyl methyl ketones. The first entry into
3-(取代的)嘧啶并[4,5 - c ]哒嗪-5,7(1 H ,6 H )-二酮(4-脱氮毒黄素的已知亚类)的改进合成被报道。该方法涉及用代表性的苯基和烷基乙二醛一水合物处理 3-甲基-6-(1-甲基肼基)尿嘧啶,后者又通过二氧化硒氧化相应的苯基和烷基甲基酮获得。还报道了首次进入 4-单取代异构体。
