Quinazolin-dione-N-3-alklyl derivatives are the core scaffolds for several categories of bioactive small molecules, but current synthetic methods are costly, involve environmental hazards, and are not uniformly scalable. Here, we report an inexpensive, flexible, and scalable method for the one-pot synthesis of substituted quinazolin-dione-N-3-alkyls (isomers of isatoic-8-secondary amides (IASAs)) from
喹唑啉二酮-N -3-烷基衍生物是几类生物活性小分子的核心支架,但目前的合成方法成本高,涉及环境危害,并且不能统一扩展。在这里,我们报告了一种廉价、灵活且可扩展的方法,用于从靛红中原位合成取代的喹唑啉-二酮-N -3-烷基(isatoic-8-仲酰胺 (IASAs) 的异构体)在酸性条件下捕获亚胺酸。我们进一步表明,该方法可用于合成多种具有药用用途的衍生物。
