Reaction of P4S10 in hot pyridine produces a crystalline solid which can be collected and used for thionations in other solvents such as acetonitrile and sulfolane. The biologically active natural products tryptanthrine, rutaecarpine, 7,8-dehydrorutaecarpine, and some related compounds have now been converted to thionated versions simply by heating the molecules with this thionating reagent in sulfolane
P 4 S 10在热吡啶中的反应产生了结晶性固体,可以将其收集并用于在其他溶剂(如乙腈和环丁砜)中进行亚硫酰化。具有生物活性的天然产物Tryptanthrine,rutaecarpine,7,8-dehydrorutaecarpine和一些相关化合物现在已经可以通过简单地在环丁砜中用该去硫剂加热分子(通常在135°C加热20分钟),然后将其转化为亚硫酰形式。在水中检查。无需层析。
