## 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
## Abstract Treated with methylthiomethylenetriphenylphosphorane, 5‐deoxy‐1,2‐O‐iso‐propylidene‐β‐D‐__threo__‐ and ‐α‐D‐__erythro__‐furanos‐3‐uloses led with good yields to a mixture of the __cis‐trans__ isomers of the corresponding methylthiovinylidenic sugars. There was no inversion of configurat
