在溶剂（如乙腈和二甲基砜）中使用P 4 S 10-吡啶络合物进行硫磺化

摘要：

四硫化二磷（P 4 S 10）中的吡啶已长期用作硫代剂。现在已经以结晶形式分离出对水分敏感的试剂，并且已经通过X射线晶体学确定了详细的结构。已经研究了这种可储存试剂的去硫能力，并将其转移到诸如乙腈之类的溶剂中，在该溶剂中已证明其在合成上是有用的并且具有非凡的选择性。它的性能已经与所谓的Lawesson试剂（LR）进行了比较。特别有趣的是在相对较高的温度（约165°C）下以二甲基砜为溶剂进行硫磺化的结果。在这些条件下，例如，a啶酮和3-乙酰吲哚可以迅速转化为相应的亚硫代衍生物。甘氨酰甘氨酸类似地得到哌嗪去甲酮。在这些温度下 LR由于快速分解而效率低下。硫代产物通常更清洁并且更容易获得，因为在结晶试剂中，常规试剂P中始终存在杂质吡啶或LR中的4 S 10已被除去。

A Rapid and Efficient Synthesis of Sulfur Analogues of Pyrimidine Bases

作者：Andrzej R. Łapucha

DOI：10.1055/s-1987-27906

日期：——

An improved procedure for thionation of some natural pyrimidine bases with tetraphosphorus decasulfide/sodium hydrogen carbonate is reported. Some substituted uracils and 2-thiouracils were converted into a series of analogues in which the oxygen at position 4 was replaced by sulfur atom. The advantage of this method of thionation over the older procedures is based on the tetraphosphorus decasulfide/sodium hydrogen carbonate mixture giving rise to excellent yields and simplified isolation of the desired pure products.

报告了一种改进的硫化天然嘧啶碱基的程序，使用了十磷化十硫化物/氢碳酸钠。某些取代的尿嘧啶和2-硫尿嘧啶被转化为一系列类似物，其中4位的氧被硫原子替代。这种硫化方法相较于旧有程序的优势在于，十磷化十硫化物/氢碳酸钠的混合物能够产生优异的产率，并简化了所需纯产品的分离。
