anti-inflammatory, and antimicrobial activities, a great deal of work has been done on the medicinal and therapeutical application of these compounds. Despite the central role of flavan-3,4-diols in the synthesis of many other classes of flavonoids, only a few methods for the preparation of these compounds have been reported. In this paper, the results on the preparation of methoxy-substituted flavan-3,4-diols
由于类黄酮表现出大量的药理特性,如抗氧化、抗炎和抗菌活性,因此人们在这些化合物的医学和治疗应用方面做了大量工作。尽管 flavan-3,4-diols 在许多其他类别的类黄酮的合成中起着核心作用,但仅报道了几种制备这些化合物的方法。在本文中,公开了通过 3 步工艺从容易获得的起始材料制备甲氧基取代的黄烷 3,4-二醇的结果,显示出自然取代模式。还表明,如果在二甲基二氧杂环丙烷 (DMDO) 环氧化过程中添加芳香亲核试剂,则 4-芳基取代的类似物可以从相应的 flav-3-ene 获得。
