retaining C2-axis of symmetry was synthesized from 1,5-dichloroanthraquinone. Optical resolution of the triptycene afforded (+)- and (−)-enantiomers. The absolute configuration of (+)-2,7-dicarboxytriptycene was determined as 1R,6R by chemical correlation with (+)-2-methoxy-7-methoxycarbonyltriptycene which has 1R,6S configuration as confirmed by chemical transformation and X-ray structure analysis using
保留 C2 对称轴的 2,7-Dicarboxytriptycene 由 1,5-二氯蒽醌合成。三苯乙烯的光学拆分提供了 (+)- 和 (-)- 对映异构体。(+)-2,7-dicarboxytriptycene 的绝对构型通过化学相关确定为 1R,6R 与具有 1R,6S 构型的 (+)-2-methoxy-7-methoxycarbonyltriptycene 经化学转化和 X 射线结构确认使用 Bijvoet 方法进行分析。以(+)-2,7-二羧基三烯为原料,制备了一系列具有1R,6R构型的2,7-二取代三烯。
