Electron impact induced fragmentations of the 1,4‐diene analogues of steroid hormones and related steroids

The electron impact induced fragmentations observed in the mass spectra of eight 1,4‐diene‐3‐ketopregnane steroids are described. The effect of hydroxyl substituents in positions 11β, 17α and 21, on the typical fragmentation pattern is analysed; in particular the ‘long range’ effect of the 17α‐hydro...
