摘要: 用发酵和化学法合成的两个3-甲酰腙-利福霉素SV样品(1#,2#)具有不同的物理化学性质,本文用多种NMR技术,如1H,13C,DEPT,1H-1H COSY,反相摸式的1H-13C COSY及远程1H-13C COSY,并结合红外及紫外一可见光谱测试结果进行综合分析,确定样1#及样2#分别为酰胺式主产品及亚胺醇式导构体。根据实验结果对样1#的异构化反应进行了初步的探讨.

Abstract: Two samples(1#,2#)of 3-formhydrazone-rifamycin SV produced by fermentation and chemieal modification have different physical and chemical properties.In this paper,their structures were determined by various kinds of NMR spcctra, such as 1H,13C,DEPT,1H-1H COSY,1H-13C COSY and LR 1H-13 C COSY in inverse mode, and by the absorption spectra of IR and UV-Vis.It was found that the two samples were the main product of amide mode (1#) and the isomer of iminol mode (2#). Based on the results of experiments,the isomerization of sample 1# was discussed.
