Abstract We discovered that α -chymotrypsin has a promiscuous ability to catalyze the cyclocondensation of aromatic and aliphatic aldehydes with 2-aminobenzamides to afford the corresponding 2,3-dihydroquinazolin-4(1 H )-ones successfully in high yields (90%–98%) under alcohol solvent. The catalytic activity of α -chymotrypsin was evaluated through investigating the temperature, the enzyme loading and the
摘要我们发现α-胰凝乳
蛋白酶具有2-
氨基苯甲酰胺催化芳香族和脂肪族醛环缩合的混杂能力,从而成功地以高收率(90%–98)获得了相应的2,3-二氢
喹唑啉-4(1 H)-酮。 %)在
酒精溶剂中。通过研究温度,酶的负载量以及酶催化反应中底物的比例来评估α-胰凝乳
蛋白酶的催化活性。就短反应时间,高收率,绿色催化剂和无需进一步纯化过程获得的清洁产物而言,本方法被证明是有效和环境友好的。
