Abstract:

The mass spectra of six acetylated glycopyranosylamine compounds were recorded. As expected of such highly substituted molecules, the spectra are complex. The molecular ion failed to appear, but the (M + 1) ion was found, even if only in traces. Several fragmentation series have been detected: some are similar to those of glycopyranose acetates, but the presence of an acetamido group on C-1 increases the number of fragmentation pathways, branching off from those found in the decomposition of acylated glycopyranoses that carry a 1-acetoxyl group. Furthermore, other series are characteristic of this type of structure. All of the results are supported by the shifting of peaks in the spectra of three acylated derivatives having O- or N-propanoyl groups, or both. © 1983.
