A variety of substituted acridones were synthesized via a one-pot, metal-free cascade reaction. In this event, the DBU-mediated addition between quinols and ortho-methoxycarbonylaryl isocyanates formed a bicyclic oxazolidinone, followed by a sequence of intramolecular condensation, tautomerization, and decarboxylation, which led to the formation of acridones. The acridones showed mild activity against
通过一锅、无金属级联反应合成了多种取代的吖啶酮。在这种情况下,DBU 介导的醌醇和邻甲氧基羰基芳基异氰酸酯之间的加成形成了双环恶唑烷酮,然后进行了一系列分子内缩合、互变异构和脱羧,从而形成了吖啶酮。吖啶酮对人巨细胞病毒表现出温和的活性。
