The enantiomers (M) and (P) of helical 9, 10-phenanthrenequinones were enriched by liquid chromatography with enantiomeric purities of 0.31 to 0.95. Their barriers to racemization (Table 2) were compared with the ones of the corresponding hydrocarbons.
螺旋9、10-菲醌的对映体(M)和(P)通过液相色谱法富集,对映体纯度为0.31至0.95。将它们的外消旋障碍(表2)与相应的烃进行了比较。
