Abstract
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-hydroxytetrahydropyran are formed in the analogous reaction of the unsubstituted 3,4-epoxy-tetrahydropyran, the mutual arrangement of the substituents in which was determined on the basis of analyzing the mass spectra.
