## 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.

Carbon-13 N M R chemical shifts in various oxazolidinea derived from pseudoephedrine and their corresponding N-borane adducts and oxazolidinium salts are examined. The observed shifts can be rationalized on the basis of steric factors, owing to the simiIarity between the borane adducts and the oxazo
