roles of the skeleton-based comparative study of electronic circular dichroism (ECD) spectra for an application of absolute configuration (AC) determination of oligostilbenoids (OS). This approach was ultimately achieved followed by the isolation and elucidation of relative configuration (RC) of upunaphenol Q (1) (new compound) and vateriaphenol A (2), namely two octamers are dimeric tetramers of resveratrol
我们调查了基于骨架的电子圆二色性(ECD)光谱比较研究在应用绝对构型(AC)测定寡麦角类固醇(OS)方面的潜在作用。最终实现了这种方法,随后分离并阐明了upunaphenol Q(1)(新化合物)和vateriaphenol A(2)的相对构型(RC)),即两个八聚体是白藜芦醇(Res)的二聚体四聚体。通用组成部分(BB)提供了进一步的洞察力,以了解在下游代谢产物中显然较小的OS是如何保守的,并提供了额外的动力来解决高度浓缩的类胡萝卜素(HCS)的AC。他们还强调了在化学文库中确定普通BB的AC的研究以及提供手性的重要性。
