摘要: 锗丙酰和取代锗丙酰氯分别与氨基酸缩合,继而水解,用三乙胺作缚酸剂,得到13个倍半氧化物.根据对以上系列化合物1H NMR、13C NMR和1H-13C COSY的分析,讨论了其核磁共振谱构关系规律,并观察到了取代氨基酸中2×CH3和乙酯的CH31H和13C NMR中出现反常现象,应用重核NMR屏蔽效应新原理对其产生的原因进行了合理阐明.

Abstract: Thirteen germanium propionyl and substituted germanium propionyl amino acid esters sesquioxide compounds were synthesized by the reaction of trichlorogermanium propionyl chloride with the corresponding amino acid esters respectively, by the use of triethylamine as agent of tied acid followed by hydrolysis. 1H NMR and 13C NMR chemical shifts of the above thirteen compounds were reported. Some relations among the substituent structure and 1H NMR, 13C NMR spectra were first discussed.
