A novel rearrangement in the gas phase under electron ionization for 3-glycosyl-5-aryl-2-isoxazolines
Some 3-glycosyl-5-aryl-2-isoxazolines were studied in the gas phase under electron ionization (EI) conditions in order to elucidate their behavior. These derivatives showed an interesting rearrangement involving opening of the heterocyclic ring with a concomitant ring closing to afford a new isoxazo...
