Unsymmetrical sulfides were first synthesized using combinations of a 1,3-dicarbonyl, an aromatic aldehyde and a thiol in the presence of 10 mol % ethanolic piperidine. These sulfides derivatives were subsequently converted into corresponding sulfones via oxidation in the presence of m-chloroperoxybenzoic acid (m-CPBA) at ice-bath to room temperature. The former reaction was achieved at room temperature
首先在10摩尔%的乙醇哌啶存在下,使用1,3-二羰基,芳族醛和硫醇的混合物合成不对称硫化物。这些硫化物衍生物随后被转化为通过氧化在存在相应的砜米氯过氧苯甲酸(米-CPBA)在冰浴至室温。前一种反应是在室温下通过一锅三组分完成的。后者是使用温和的反应条件以高收率获得的,可以灵活选择多种底物。研究了新合成的砜衍生物对原生动物寄生虫利什曼原虫donovani的抗菌性能。,是内脏利什曼病(VL)的病原体。发现九种砜衍生物是有效的并且表现出显着的抗微生物活性。此外,这些化合物对鼠腹膜巨噬细胞无毒,因此消除了宿主细胞中潜在的细胞毒作用。这些化合物可被指示为内脏利什曼病治疗的潜在先导。
