The absolute configurations of two estrogenic nonylphenols were determined in solution. Both nonylphenols, NP35 and NP112 could not be crystallized so that only solution methods are able to solve directly the question of absolute configuration. The conclusion based on experimental and calculated optical rotation and VCD data for the nonylphenol NP35 was independently confirmed by another study using
在溶液中测定了两种雌激素壬基酚的绝对构型。壬基酚 NP35 和 NP112 都不能结晶,因此只有溶液法才能直接解决绝对构型问题。基于壬基酚 NP35 的实验和计算的旋光度和 VCD 数据的结论由另一项使用樟酰衍生物和所得晶体的 X 射线分析的研究独立证实。在 NP112 的情况下,实验旋转数据是不确定的。然而,实验和计算 VCD 数据之间的比较允许确定绝对配置。
