An efficient synthesis of 2,4,5-trisubstituted thiazoles via the reaction of α-nitroepoxides and thioureas under mild conditions has been developed. This reaction proceeded well at room temperature, to afford products in excellent yields for a wide range of substrate, and a possible mechanism has also been proposed.
已经开发了在温和条件下通过α-硝基环氧化物与硫脲反应有效合成2,4,5-三取代噻唑的方法。该反应在室温下进行得很好,从而为广泛的底物提供了具有优异收率的产物,并且还提出了一种可能的机理。
