Abstract Most of the fragments formed during electron-impact mass spectrometry of alditol acetates have odd mass numbers, but fragments having even mass numbers are also formed. The origin of these fragments has been rationalized for fully acetylated 1 -deoxyhexitols by using deuterated analogues and studying the metastable transitions. The previously known di- O -benzylidene- 1-deoxy- l -gulitol was shown
摘要乙醛糖醇乙酸酯的电子轰击质谱中形成的大部分碎片均具有奇数质量,但也形成了具有偶数质量的碎片。通过使用氘代类似物并研究亚稳转变,已将这些片段的来源合理化为完全乙酰化的1-脱氧己糖醇。先前已知的二-O-亚苄基-1-脱氧-1-葡糖醇显示为3,5:4,6-二-O-亚苄基衍生物。
