| heal.abstract |
The electron impact ionization mass spectra of 6-carbamoyloxy-3-oxo-3,6-dihydro-2H-pyrans show a weak molecular ion peak and a base peak of m/z 84 resulting from a retro Diels-Alder fragmentation. The bicyclic system 5H-pyrano[3,2-d]oxazole-2,6-dione gives a characteristic fragmentation pattern with a very stable fragment of oxazolenone. |
