The preparation and base solvolyses of some S-phosphorylated derivatives of 2-mercaptoethanol and related compounds are reported. The fully esterified derivatives possessing favourable stereochemistry rearrange to the O-phosphorylated derivatives which then undergo elimination of an episulphide. In contrast, the mono-esterified derivatives eliminate alkoxide to give the cyclic intermediate [graphic
报道了2-巯基乙醇的一些S-磷酸化衍生物和相关化合物的制备和碱溶剂化。具有有利的立体化学的完全酯化的衍生物重新排列为O-磷酸化的衍生物,然后将其消除上环硫化物。相反,单酯化的衍生物消除了醇盐,得到了环状中间体[图解省略](:O)·O –。这会经历亲核性攻击,优先进行P-O裂解,因此与无环类似物的行为形成对比。这些反应以五价中间体的形式讨论。
