天然产物绝对构型的确定是天然产物结构解析中的一个难点。当手性化合物具有合适的发色团时,电子圆二色性(ECD)可以提供一种强有力的方法来确定它们的绝对构型。最近,ECD计算的含时密度泛函理论(TDDFT)已被越来越多地使用。在本综述中,我们给出了几个例子,最近的研究使用TDDFT计算的ECD光谱的AC测定天然产物。
Determination of the absolute configuration (AC) is often a challenging aspect in the structure elucidation of natural products. When chiral compounds possess appropriate chromophore(s), electronic circular dichroism (ECD) may provide a powerful approach to the determination of their absolute configuration. Recently, ECD calculations by time-dependent density functional theory (TDDFT) have come to be used more commonly. In the present review, we give several examples of recent studies using TDDFT-calculated ECD spectra for the AC determination of natural products.
