to give various 3-substituted quinazolinones, respectively. The structures of all the synthesized compounds were confirmed by spectral data and have been screened for antibacterial and antifungal activity.
3-Chloro-1-benzothiophene-2-carbonylchloride 1 在吡啶中与邻氨基苯甲酸反应得到化合物 2。这项工作的主要目的是研究这种 4H-3,1-benzoxazin-4-one 对氮亲核试剂的行为. 该化合物与芳香胺、盐酸羟胺、甲酰胺、巯基乙酸、氨基硫脲和酰氯反应,分别得到各种3-取代的喹唑啉酮。所有合成化合物的结构均通过光谱数据确认,并已筛选出抗菌和抗真菌活性。
