## Abstract The electron impact mass spectra of 29 oxazolidines derived from sugars were examined. Four general pathways of fragmentation were encountered, the importance of which depends on the nature of the different substitutents.

The synthesis of optically pure 4,5-dihydro-3(2H)-pyridazinones substituted at C-4, which can be considered conformationally restricted cyclic Glu derivatives, has been accomplished by the asymmetric g-alkylation of a,b-unsaturated glutamyl sultams under PTC conditions followed by reaction with hydr
