(S)‐(−)‐1‐phenylethyliso‐cyanate, which were studied by NMR. The comparison of NMR data and molecular mechanics calculations allowed us to determine the absolute configuration of corresponding alcohols. Finally, x‐ray results were in agreement with the absolute configuration proposed from the NMR spectra. Copyright © 1999 John Wiley & Sons, Ltd.
合成了 2,2-二甲基-1-(1-萘基)丙醇,并通过手性 HPLC 分离了相应的对映异构体。这些对映异构体通过与 (S)-(-)-1-苯基乙基异氰酸酯反应得到非对映异构氨基甲酸酯,并通过 NMR 进行研究。核磁共振数据和分子力学计算的比较使我们能够确定相应醇的绝对构型。最后,X 射线结果与 NMR 光谱提出的绝对构型一致。版权所有 © 1999 John Wiley & Sons, Ltd.
