Abstract A synthesis of novel bis(sulfanediyl)bis(tetrahydropyrimido[4,5-b]quinoline-4,6-diones), linked to aryl, heteroaryl, and spirocyclic-oxindole moieties at position-5, as novel hybrid molecules was reported. 2,2'-(Butane-1,4-diylbis(sulfanediyl))bis(6-aminopyrimidin-4(1H)-one) was utilized as a precursor to our target compounds via a multicomponent reaction with two equivalents of both of the
摘要 据报道,合成了新型双(硫烷二基)双(四氢嘧啶并 [4,5 - b ] 喹啉-4,6-二酮),在 5 位与芳基、杂芳基和螺环-羟吲哚部分连接,作为新型杂化分子。2,2'-(Butane-1,4- diyl bis (sulfanediyl)) bis (6-aminopyrimidin-4(1 H )-one) 被用作我们目标化合物的前体,通过多组分反应与两个当量的适当的醛和二甲酮。或者通过适当的 5-芳基-2-硫代六氢嘧啶[4,5- b]的双-(烷基化)获得目标化合物]quinoline-4,6-dione 与 1,4-dibromobutane 在中等碱性介质中。
