ABSTRACT A straightforward and convenient synthesis of symmetrical thiourea derivatives by the reaction of primary amines and carbon disulfide in biocompatible basic choline hydroxide is presented. A variety of biologically important thiourea derivatives can be obtained in good to excellent yields without a tedious work-up under mild reaction conditions. A series of primary aliphatic and aromatic amines
Malonicacid and derivatives have been well-known to undergo monodecarboxylation under relatively mild conditions and have been exclusively used as a C2 synthon. We report herein their new application as a C1 synthon via double decarboxylation promoted by sulfur and dimethyl sulfoxide. In the presence of amines as nucleophiles, a wide range of thioureas and thioamides as well as N-heterocycles were
众所周知,丙二酸及其衍生物在相对温和的条件下进行单脱羧,并专门用作C 2合成子。我们在此报道了它们作为 C 1合成子的新应用,通过硫和二甲亚砜促进的双脱羧作用。在胺作为亲核试剂存在的情况下,在温和的加热条件下,可以以良好至优异的产率获得各种硫脲和硫代酰胺以及N-杂环。
