aliphatic amines with the reagent H2S-CH2O (2:3) in aqueous medium mainly gave substituted dithiazines; oxathiazines and dioxazines were obtained from butylamine and ethanolamine. Under the chosen reaction conditions, ethylenediamine was converted into 5-[2-(perhydro-1,3,5-dithiazin-5-yl)ethyl]perhydro-1,3,5-dithiazine or substituted thiazetidine and oxazetidine, depending on the order of mixing of
在水性介质中用试剂 H2S-CH2O (2:3) 对脂肪族伯胺进行环硫甲基化,主要得到取代的二噻嗪;恶噻嗪和二恶嗪由丁胺和乙醇胺得到。在选定的反应条件下,乙二胺转化为 5-[2-(perhydro-1,3,5-dithiazin-5-yl)ethyl]perhydro-1,3,5-dithiazine 或取代的噻唑烷和氧氮杂环丁烷,具体取决于起始试剂的混合顺序。
