allowed the determination of the absolute configurations of the original resveratrols via comparison of experimental and theoretical electronic circular dichroic spectra. Notably, the absolute configuration of pauciflorol B was identified using this novel procedure, which is the first application of dehydroxylated derivatives for the determination of the absolute configuration of naturally occurring polyphenols
天然存在的低聚白藜芦醇衍生物的脱羟基作用导致形成了具有显着降低的主要稳定构象异构体的化合物。另外,通过比较实验和理论电子圆二色性光谱,脱羟基反应可以确定原始白藜芦醇的绝对构型。值得注意的是,用这种新颖的方法鉴定了紫杉醇B的绝对构型,这是脱羟基衍生物在确定天然多酚的绝对构型中的首次应用。
