ethanol or acetic acid. Upon heating 3,3'-arylidenebis-4-hydroxycoumarins, and tetrakis-4-hydroxycoumarin derivative in anhydride acetic acid, the epoxydicoumarins (9-16) were formed. From a study of nuclear magnetic resonance and infrared spectra, intramolecularly hydrogen-bonded structures are proposed for the dicoumarols (1-8). A possible relationship between such hydrogen-bonded structures and the
当4-羟基香豆素和在邻位,间位或对位含有不同基团的芳族醛在沸腾的乙醇中冷凝时,最终的最终产物是不同的取代的3,3'-亚芳基双-4-羟基香豆素(1-7)和四--4-羟基香豆素衍生物8或醋酸。在酸酐中加热3,3′-亚芳基双-4-羟基香豆素和四--4-羟基香豆素衍生物,形成环氧双香豆素(9-16)。通过对核磁共振和红外光谱的研究,提出了双香豆酚的分子内氢键结构(1-8)。提出了这样的氢键结构与化合物1-8的抗微生物和抗氧化活性之间的可能关系。
