5-Hydroxy-2-methyl-4-(alkylamino)-2H-pyran-3(6H)-one: A New Sugar-Derived Aminoreductone
摘要:
2,3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (3) is one of the main products obtained from glucose under the conditions of the Maillard reaction. Heating of 3 in the presence of primary amines leads to the formation of 5-hydroxy-2-methyl-4-(alkylamino)-2H-pyran-3(6H)-one (11). These new aminoreductones can also be isolated from glucose/amine reaction mixtures.
