Abstract A green synthetic route to the facile one-pot multicomponentsynthesis of pyrano[2,3‐d]pyrimidines and pyrido[2,3‐d]pyrimidines have been developed using magnetized deionized water (MDW) as a green solvent under catalyst-free conditions. All reactions carried out in a short period of time and the products are obtained in high-to-excellent yields. The developed synthetic technique offers numerous
摘要 在无催化剂的情况下,使用磁化去离子水(MDW)作为绿色溶剂,已经开发出一条绿色的合成路线,可以轻松实现一锅多位合成吡喃并[2,3- d ]嘧啶和吡啶并[2,3- d ]嘧啶。情况。所有反应都在短时间内进行,并且以高至优异的产率获得了产物。与传统的合成方法相比,发达的合成技术具有许多优点,包括环保,清洁合成,简单,成本低,反应时间短,反应产率高以及后处理容易。此外,通过监测普通去离子水和MDW中反应混合物的吸收光谱的变化,通过分光光度法跟踪反应速率。 图形摘要
