groups to yield pyrimido[2,1-b][1,3,5]thiadiazines via the multicomponent double Mannich reaction. The structure of 3-benzyl-8-nonafluorobutyl-3,4-dihydro-2H,6H-pyrimido[2,1-b][1,3,5]thiadiazin-6-one was studied by the X-ray diffraction analysis. The use of ethylenediamine in these reactions yields 3,3′-ethane-1,2-diyl-bis(pyrimido[2,1-b]thiadiazinone) as a result of the bis-double Mannich cyclocondensation
6-多氟烷基-2-硫尿嘧啶与2-巯基和3-氨基到屈服嘧啶并[2,1-B]在EtOH(MeCN中)和甲醛伯胺反应经由该多组分双曼尼希[1,3,5]噻二嗪反应。3-苄基-8-九氟丁基-3,4-二氢-2H,6H-嘧啶并[2,1-b] [1,3,5]噻二嗪烷-6-酮,研究了X射线衍射分析的结构。在这些反应中的产率3,3'-乙烷-1,2-二基 - 双(嘧啶并[2,1-b]噻二嗪酮)作为双 - 双曼尼希环缩合的结果,使用乙二胺。8多氟烷嘧啶并[2,1-b]噻二嗪表现出弱抗结核活性。
