stereochemicak Effects in Mass Spectromery 15.——Thermospray Mass spectra of Methyl Glycosides of Monosaccharides

  • 摘要: 本文报道了六种己糖甲基苷和四种戊糖甲基苷的热喷雾质谱,不同构型的差向异构体产生的裂片离子[M+NH_4—H_2O]~+[M+NH_4—2H_2O]~+或[M+NH_4—H_2O—NH_3]~+的相对丰度各不相同,从立体化学的角度讨论了产生这些差别的原因。
    Abstract: In present work, the thermospray mass spectra of methyl glycosides of six hexsoses and four pentoses have been measured. The relative abundances of fragment ions, (M+NH_4-H_2O)~+, (M+NH_4-2H_2O)~+ or (M+NH_4-H_2O-NH_3)~+ of epimers of these glycosides are quite different from each other (see Table 1). These phenomena have been discussed on a stereochemieal view.
