T. Knerr et al., HYDROXY-2-METHYL-4-(ALKYLAMINO)-2H-PYRAN-3(6H)-ONE - A NEW SUGAR-DERIVED AMINOREDUCTONE, Journal of agricultural and food chemistry, 42(8), 1994, pp. 1657-1660
2,3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (3) is one of the ma
in 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 hydroxy-2-methyl-4-(alkylamino)-2H-pyran-3(6H)-one (11).
These new aminoreductones can also be isolated from glucose/amine rea
ction mixtures.
