the diastereoisomers has been determined by X-ray crystallography. The absolute configurations of the resolved acids have been established by a comparative study of their CD curves. The antiinflammatory and analgesic properties of these compounds as functions of their structure and stereochemistry are discussed.
已经制备了各种2-烷基-α-甲基-和2-烷基茚满-5-乙酸。可以以两种非对映异构形式存在的酸,无法通过结晶或色谱分离,可以在Eu(dpm)3存在下通过NMR在其混合物中进行分析。通过用具有各种活性碱的盐将混合物拆分后得到的对映异构体,可以重构出两个纯的外消旋的2-异丙基-α-甲基-茚满-5-乙酸。非对映异构体盐之一的两个不对称中心与各种活性碱的相对构型。非对映异构体之一的两个不对称中心的相对构型已经通过X射线晶体学确定。通过对它们的CD曲线的比较研究已经确定了拆分酸的绝对构型。
