Abstract Fragmentation reactions of β-hydroxymethyl-, β-acetoxymethyl-and β- benzyloxymethyl-butenolides and the corresponding γ-butyrolactones were investigated by electrospray ionization tandem mass spectrometry (ESI-MS/MS) using collision-induced dissociation (CID). This study revealed that loss of H 2 O [M+ H− 18]+ is the main fragmentation process for β-hydroxymethylbutenolide (1) and β-hydroxymethyl-γ- ...
