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。
