摘要： 合成了8对非对映异构体酰胺,测定了它们的13CNMR化学位移值和相应的非对映异构体基团的化学位移差。根据实验数据提出一种分子优势构象与13CNMR化学位移不等性的相关模型。

Abstract: Eight pairs of diastereomeric amides have been prepared,and their 13C NMR chemical shift data and the corresponding shift differences between each pair of diastereomers were reported.Acorrelation model was proposed on the basis of the preferred conformation with the observed 13C NMR chemical shift nonequivalences of these amides.

Key words: Amides, Diastereomer, 13CNMR chemical shift differences, Preferred conformation model
