isoxazole and a benzoxazinone ring as a prime motif was rationally designed and synthesized. There is nothing in the literature about such α,β-unsaturated ketones. These compounds were synthesized using a Claisen–Schmidt condensation reaction of the ketone precursor with different aromatic aldehydes using ethanol as solvent and piperidine as a base. Our procedure offers easy access to isoxazole and benzoxazinone
合理设计并合成了一系列以
异恶唑和苯并恶嗪酮环为主要基序的
查尔酮新型杂环类似物。文献中没有关于这种α,β-不饱和酮的文献。这些化合物是使用
乙醇作为溶剂,以
哌啶为碱,通过酮前体与不同芳族醛的克莱森-施密特缩合反应合成的。我们的方法可轻松获得基于
异恶唑和苯并恶嗪酮的
查尔酮衍
生物,在温和条件下,在16分钟内收率可达81–93%。从21种化合物中筛选出11种化合物的抗菌活性。在筛选出的化合物中,化合物5aj,5ak和5bj与标准药物相比,对MIC表现出优异的抗菌活性:分别为0.34、0.59和0.74 mg ml -1。
