A series of novel 10-thiaisoalloxazine derivatives bearing an alkoxymethyl or benzyloxymethyl moiety at the N-1 position has been synthesized through the bromination of 1-substituted-5-hydroxyuracils and subsequent condensation with aminobenzenethiol in a one-pot reaction. Contrary to the previous report, the formation of intermediary 5,6-diethoxy-5-hydroxy-5,6-dihydrouracil seems to be not the necessary
通过1-取代的5-羟基尿嘧啶的溴化和随后与氨基苯硫醇的一锅反应缩合,已经合成了一系列在N-1位带有烷氧基甲基或苄氧基甲基部分的新型10-噻吩异恶嗪衍生物。与先前的报告相反,中间体5,6-二乙氧基-5-羟基-5,6-二氢尿嘧啶的形成似乎不是形成硫代异恶嗪的必要因素,因为该反应在四氢呋喃(THF)或乙腈中进行比使用乙醇更顺滑。基于对病毒诱导的细胞病变活性的抑制活性,评估了淋巴细胞中噻吩异恶嗪衍生物的抗人免疫缺陷病毒(HIV)-1活性。在衍生物中,化合物6、7
