Aldohexoses react with primary long chain alkylamines at room temperature, giving N- alkylglycosylamines in good yields. Ketohexoses react with primary long chain amines at room temperature to form the corresponding N-alkylketosylamines, as well as substantial amounts of products formed from one mole of sugar and two moles of amine. At higher temperatures several moles of amine may react with one mole of either aldohexose or ...
