carbon, and both its enantiomers have been found in nature. Enantiomeric pure (+)-(1) and (−)-(1) were successfully prepared by racemic synthesis followed by enantiomeric separation in a chiral HPLC system. Their absolute configurations were clarified by the vibrational circular dichroism technique using their methyl esters 2 and lactones 3. Their inhibitory activities against the interaction of p53–HDM2
己基衣康酸(1)是一种具有手性碳的引人入胜的天然产物,并且其两种对映异构体均已在自然界中发现。通过外消旋合成,然后在手性HPLC系统中进行对映体分离,成功制备了对映体纯(+)-(1)和(-)-(1)。通过使用它们的甲酯2和内酯3的振动圆二色性技术阐明了它们的绝对构型。还检查了它们对p53–HDM2相互作用的抑制活性。
