An efficient one-pot synthesis of 2,3-dihydroquinazoline-4(1H)-one derivatives 4a–l is described using SBA-Pr-SO3H as a heterogeneous acid catalyst. The present methodology resulted in various derivatives of 2,3-dihydroquinazoline-4(1H)-one in good yield via a three-component reaction of isatoic anhydride, aldehydes and ammonium acetate. SBA-Pr-SO3H played a significant role as an efficient mesoporous
使用SBA-Pr-SO 3 H作为非均相酸催化剂描述了有效的一锅合成2,3-二氢喹唑啉-4(1 H)-一衍生物4a-1。本方法学通过二酸酐,醛和乙酸铵的三组分反应以高收率得到了2,3-二氢喹唑啉-4(1 H)-one的各种衍生物。SBA-Pr-SO 3 H由于其孔径为6 nm而在有效的介孔催化剂中起着重要作用。此外,还研究了产品的UV-Vis光谱,以研究其作为UV吸收剂的应用。
