Two metabolites of trithiozine, namely 4‐(3,5‐dimethoxy‐4‐hydroxythiobenzoyl)morpholine S‐oxide (2a) and 4‐(3,4,5‐trimethoxythiobenzoyl)morpholine S‐oxide (2b), were synthesized by oxidation of the thioamides 1a, b or, in the case of 2b, by reaction of E‐ and Z‐(3,4,5‐trimethoxyphenyl)(methylthio)sulfine (4) with morpholine. Both procedures afford the compounds 2a, b as single isomers having the same
通过氧化合成了三硫嗪的两种代谢物,即 4-(3,5-二甲氧基-4-羟基硫代苯甲酰基)吗啉 S-氧化物(2a)和 4-(3,4,5-三甲氧基硫代苯甲酰基)吗啉 S-氧化物(2b)硫代酰胺 1a、b 或在 2b 的情况下,通过 E-和 Z-(3,4,5-三甲氧基苯基)(甲硫基)亚砜 (4) 与吗啉反应。两种方法均得到化合物2a、b,为在亚磺基具有相同构型的单一异构体。与其他具有已知结构的芳族亚砜在镧系元素位移试剂存在下的核磁共振行为相比,2b 的芳族邻质子的核磁共振行为支持 Z-构型。
