Synthesis of thioureas


Recent Literature

The combination of sulfur and chloroform enables an efficient and practical synthesis of a thiocarbonyl surrogate. Various thiocarbamides and oxazolidinethiones have been synthesized, including chiral thiourea catalysts and chiral oxazolidinethione auxiliaries with high selectivity.
