A novel and facile metal-free method for the green synthesis of 2-amino-4-arylthiazole derivatives through the three-component cascade reaction of aromatic methyl ketones, elemental sulfur and cyanamide is reported. One CN bond and two CS bonds were formed in one-pot protocol without using catalysts.
报道了一种通过芳族甲基酮、元素硫和氰胺的三组分级联反应绿色合成 2-氨基-4-芳基噻唑衍生物的新型、简便的无金属方法。在不使用催化剂的情况下,在一锅法中形成一个 C N 键和两个 C S 键。
Synthesis and Antibacterial Activity of Benzazolyl Azolyl Sulfamoyl Acetamides
A new class of benzazolyl azolyl sulfamoyl acetamides was prepared from azolyl sulfamoyl acetates and benzazolyl amines in the presence of KOtBu in tetrahydrofuran. Compounds with benzothiazole‐thiazole, benzimidazole‐thiazole, benzothiazole‐imidazole, and benzimidazole‐imidazole moieties exhibited excellent antibacterial activity against Bacillus subtilis.
