through the partial reduction of isothiocyanates with the in situ generated Schwartz reagent. The high electrophilicity of the starting materials enables the straightforward addition of the hydride ion, thus constituting a reliable and high-yielding method for obtaining variously functionalized thioformamides. Sensitive chemical groups to the reduction conditions such as nitro, ester, alkene, azo, azide and
通过完全原位生成的Schwartz试剂将异硫氰酸酯部分还原,可以轻松地在完全化学控制下制备硫代甲酰胺。起始材料的高亲电性使氢化物离子的直接添加成为可能,从而构成了一种可靠且高产率的方法,可用于获得各种官能化的硫代甲酰胺。对还原条件敏感的化学基团,例如硝基,酯,烯烃,偶氮,叠氮化物和酮基,不会干扰该方法的化学选择性。此外,起始材料中体现的立体化学信息完全保留在最终产品中。还简要讨论了所选硫代甲酰胺模板的合成潜力。
