Direct reaction of isocyanides with some sulfenic-acid-generating sulfoxides led to the effective formation of the corresponding thiocarbamic acid S-esters in good to high yields. A multicomponent reaction involving isocyanide, sulfoxide, and a suitable nucleophile has also been developed, providing ready access to a diverse range of sulfur-containing compounds, including isothioureas, carbonimidothioic
异氰酸酯与一些产生亚磺酸的亚砜的直接反应导致以高至高收率有效地形成相应的硫代氨基甲酸S-酯。还开发了涉及异氰酸酯,亚砜和合适的亲核试剂的多组分反应,可轻松获得各种范围的含硫化合物,包括异硫脲,碳亚氨基硫代酸酯和羧亚氨基硫代酸酯。
