A series of anomeric unsaturated C ‐glycosides were studied by negative ion mass spectrometry following keV ion bombardment The compounds bearing an acidic hydrogen show a prominent [M H] − peak; in the other cases, the [M H] − peak is of very low intensity. A retro‐Diels–Alder fragmentation and the abstraction of a hydrogen atom from the aglycon residue are observed in all cases.
