for the synthesis of both isourea and isothiourea in a three-component coupling reaction by treating alcohols or thiols respectively with N,N-dibromoarylsulfonamides and isonitrile and in the presence of K2CO3. This metal-free process proceeds via carbodiimide intermediate at room temperature within a very short reaction time. A library of sulfonylisoureas and isothioureas has been made using this synthetic
已经开发了一种在三组分偶联反应中合成异脲和异硫脲的统一方法,方法是分别用N,N-二溴芳基磺酰胺和异腈在 K 2 CO 3存在下处理醇或硫醇。这种无金属工艺在室温下通过碳二亚胺中间体在非常短的反应时间内进行。使用这种合成方案制备了磺酰异脲和异硫脲库,具有广泛的底物范围,产率从好到高。
