Thiazol‐2‐imine derivatives were synthesized in an easy and efficient route from the regioselective one‐pot three‐component reaction of aryl amine, alkylisothiocyanate, and various α‐haloketones in [omim][OH] basic ionic liquid. Recyclable reaction media, catalyst free, and short reaction times are the main advantages of this protocol. This method produces the products at room temperature in excellent yields (68–96%)
噻唑-2-亚胺衍生物是在[omim] [OH]碱性离子液体中,通过芳基胺,烷基异硫氰酸酯和各种α-卤代酮的区域选择性单锅三组分反应合成的,简便而有效的途径。可循环使用的反应介质,无催化剂,反应时间短是该方案的主要优点。这种方法在室温下以极高的收率(68–96%)生产产品。此外,通过X射线晶体学分析确定了目标化合物6b。
