Mass-spectrometric study of the cleavage products of 3,4-epoxytetrahydropyrans by amines
Only 4-methyl-3-amino-4-hydroxytetrahydropyrans are formed when the oxide ring of 4-methyl-3,4-epoxytetrahydropyran is opened by ammonia and amines. The structural isomers of 4-amino-3-hydroxy-and 3-amino-4-hy...

The effect of the relative location of the double bond and the alkoxy group on the mass-spectrometric behavior of alkoxydihydropyranes
The mass spectra ofthree 6-alkoxy-Δ3-dihydropyranes and of three 6-alkoxy-Δ2-dihydropyranes have been studied. As distinct from the previously studied 2-alkoxy-Δ3-dihydropyranes, the dominant fragmentation patter...

Mass spectrometric study of desoxyamino sugars
The mass spectra of ten 3,4-didesoxy-3-amino sugars have been studied. A novel type of ring cleavage was detected in the molecular ions of these compounds, which had not been encountered in previously studied ...
