3-methyl[1,3]thiazolo[3,2-a]-[3,1]benzimidazol-9-ium salt and the alkanethiol derivative under mild conditions. The alkanethiol and the heteroaromatic salt are easily separated by a simple extraction process. The intermediate thiazolium quaternary salts resulting from the first reaction step can be isolated in quantitative yields, affording an odourless protected form of the thiols.
描述了一种使用标题化合物的顺序烷基化,然后闭环以定量得到相应的 3-甲基 [1,3] 噻唑并 [3,2] 来制备非常纯的线性烷硫醇和线性 α,ω-烷二硫醇的新方法-a]-[3,1]苯并咪唑-9-鎓盐和链烷硫醇衍生物在温和条件下。烷硫醇和杂芳族盐很容易通过简单的萃取过程分离。可以定量产率地分离由第一反应步骤产生的中间体噻唑鎓季盐,得到硫醇的无味保护形式。
