Synthesis and mass spectra of some αβ-unsaturated γ-lactones and γ-lactams

Abstract
Migration of an alkyl or phenyl group from the γ-position of a number of γ-disubstituted αβ-unsaturated γ-lactones and one γ-lactam upon electron impact has been proved by high resolution and 18O-labelling studies and by the observation of metastable ions. Improved methods for the synthesis of such compounds uncontaminated by their dihydro-derivatives are described.
