The electron impact induced fragmentations of the title compound, its methyl ester, its three hydroxy derivatives, namely, 3‐hydroxy α‐ and β‐hydroxy, their acetyl methyl esters and its 2,3‐dehydro derivative, have been studied in detail. Among the uncommon features of the observed processes were methyl acetate and C‐2 and C‐3 hydrocarbon expulsions and a few novel rearrangements. The ion at m/z 131 appeared as the terminal for many fragmentation sequences.
