**Electron Impact Mass Spectrometry of the 3‐Desoxy‐1,2: 5,6‐di‐__O__‐isopropylidene‐3‐methylidene‐δ‐D‐hexofuranose and Some C(3′)‐Substituted Analogues** The mass spectra of the 3‐desoxy‐1,2:5, 6‐di‐__O__‐isopropylidene‐3‐methylidene‐ α‐D‐__ribo__‐hexofuranose and of some C(3′)‐mono‐ and ‐disubsti
## Abstract The mass spectra of the O‐isopropylidene derivatives of __threo__‐ and __erythro__‐furanose and those of the four C(4) methylated stereoisomers have been studied. Fragmentation modes based upon deuterium labelling, metastable peaks and high‐resolution measurements are proposed. Each ste
