The mass spectra of acetylated and propanoylated aldopyranosylamines

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...

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.
