Abstract

Stäng
- Trimethylsilylation of methylated aldohexopyranoses and mass spectrometry of the mixed derivatives permits a simple determination of the number and location of the methoxyl groups. Advantage is taken of the close analogy between the fragmentation of the mixed derivatives and of fully methylated species. The fragmentation is discussed on the basis of the spectra of twenty species. Spectra of derivatives of hexofuranoses and ethylated hexopyranoses indicate that the method can be applied to these species as well.
