A practical and efficient methylthiolation that employed the typical Bunte salt sodium S-methyl sulfothioate as the sulfur source was described. This reagent could react with a variety of compounds such as alkynes, 1,3-diketones, thiols, selenol and H-phosphine oxides, affording methylthiolated products in moderate to excellent yields. The advantages such as easy preparation, air- and moisture-stability
描述了使用典型的 Bunte 盐S-甲基硫代磺酸钠作为硫源的实用且有效的甲基硫醇化。该试剂可以与多种化合物反应,如炔烃、1,3-二酮、硫醇、硒醇和H-氧化膦,以中等至优异的收率提供甲基硫醇化产物。制备简单、空气和水分稳定、官能团耐受性高等优点表明该试剂具有广泛应用于有机合成的潜力。值得注意的是,厄洛替尼药物分子的后期修饰证明了该试剂的稳健性。
