A new and direct synthetic method was developed for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones by condensing 2-aminobenzamide and aldehydes in ethanol using thionyl chloride as a catalyst at room temperature. The simple reaction conditions, small timing, easy work up and very good yields are the greatest advantages of this methodology. By utilizing the approach six novel derivatives of 2-aryl-2,3-dihydroquinazolin-4(1H)-ones (3a-3f) were synthesized. All the compounds were tested for their anticancer activity on A549 cell line and antioxidant activity by using DPPH method. Compounds 3c (74.22 %) and 3e (73.45 %) showed better anticancer activity towards the A549 cell line.
在室温下,以硫酰氯为催化剂,通过在乙醇中缩合 2- 氨基苯甲酰胺和醛,开发了一种新的直接合成 2,3-二氢喹唑啉-4(1H)-酮的方法。这种方法的最大优点是反应条件简单、时间短、易于操作且收率极高。利用这种方法合成了六种 2-芳基-2,3-二氢喹唑啉-4(1H)-酮的新型衍生物 (3a-3f)。采用 DPPH 法测试了所有化合物对 A549 细胞系的抗癌活性和抗氧化活性。化合物 3c (74.22 %) 和 3e (73.45 %) 对 A549 细胞株表现出更好的抗癌活性。
