摘要
测定了１２个标题化合物的核磁共振谱，报道了它们的１Ｈ和１３Ｃ化学位移以及定量分析数据。在吡啶中，Ｈ－４的两组非对映体峰的化学位移差值随Ｈａｍｍｅｔｔ常数（σ）的减小而增大。２－芳基上取代基的位置和性质以及使用的溶剂都能够影响非对映体２Ｒ，４Ｒ 和 ２Ｓ，４Ｒ在溶液中的相对含量。
NMR spectra of 12 titled compounds are determined. The chemical shifts of 1H and 13C and the data of quantitative analysis are reported. The chemical shift difference of two groups of H-4 peaks for the diastereomers increases with reducing in Hammett constant (σ) of substituents. The relative contents of diastereomers, 2R 4R and 2S 4R, in solution are influenced by both the solvents used and the characteristics and locations of substituents on 2-aryl.
