Development of a green, concise synthesis of nicotinamide derivatives catalysed by Novozym® 435 from <i>Candida antarctica</i> in sustainable continuous-flow microreactors
activities, such as anti-inflammatory and antitumor activity. In this paper, a green, concise synthesis of nicotinamide derivatives in sustainable continuous-flow microreactors catalysed by Novozym® 435 from Candidaantarctica has been developed. Application of an easily obtainable and reusable lipase in the synthesis of nicotinamide derivatives from methyl nicotinate and amines/benzylamines reacted for 35
越来越多的研究表明,许多烟酰胺衍生物表现出广泛的生物活性,例如抗炎和抗肿瘤活性。本文开发了一种在可持续连续流动微反应器中由来自南极假丝酵母的 Novozym® 435 催化的烟酰胺衍生物的绿色、简洁合成方法。应用易于获得且可重复使用的脂肪酶来合成烟酰胺衍生物,烟酸甲酯与胺/苄胺在 50 °C 下反应 35 分钟,获得了较高的产物收率 (81.6-88.5%)。采用环保叔戊醇作为反应介质。与间歇法相比,反应时间显着缩短,产品收率显着增加。这种创新方法为新型烟酰胺衍生物的药物合成和进一步活性研究提供了一种有前景的绿色、高效、快速的合成策略。
