Abstract

Characterization of stereoisomeric 3,4-dideoxy-3-fluoro-hexoses has been carried out using fast-atom bombardment. Diagnostic fragments were observed in the daughter-ion spectra of the [M - H]- and [M + H]+ ionic species. Notable differences were also observed in the relative abundances of ionic species corresponding to [M - H]-, [M - H - HF]- and [C11H11O2]- ions.

摘要

已使用快原子轰击法对立体异构的3,4-二脱氧-3-氟己糖进行了表征。在[M - H]-和[M + H]+离子物种的子离子光谱中观察到了诊断性碎片。在对应于[M - H] -、[M - H - HF] -和[C11H11O2] -离子的离子物种的相对丰度中也观察到了显著差异。
