Hexahydrocurcumin (HHC) and octahydrocurcumin (OHC) were synthesized, and their enantiomers were separated using supercritical fluid chromatography. The absolute configurations (ACs) of HHC and OHC were independently determined using experimental measurements and quantum theoretical predictions of vibrational circular dichroism, electronic circular dichroism, and optical rotatory dispersion. These
合成了六氢姜黄素 (HHC) 和八氢姜黄素 (OHC),并使用超临界流体色谱分离了它们的对映体。HHC 和 OHC 的绝对构型 (AC) 是使用振动圆二色性、电子圆二色性和旋光色散的实验测量和量子理论预测独立确定的。这些研究导致 (−)-( R )-HHC 和 (+)-( R , R )-OHC 的 AC 分配。OHC 的 AC 由单晶 X 射线衍射确定的结构进一步证实。
