Glycosylation, a part of the Maillard reaction, occurs non-enzymatically in food and biological processes. The selectivity of N-glycosylation was analyzed based on the reactivity of monosaccharides with aromatic amines, including aromatic amino acids, and the degree of molecular interaction (MI) measured using liquid chromatography. Furthermore, the chemical structures of reaction products were determined using X-ray crystallography and/or NMR. The possible reaction products were estimated in silico using the optimized energy values of different conformations. The MI energy values of amino groups and saccharides were calculated using in silico analysis using a model phase. Saccharides having larger MI values easily produced stable crystals of N-glycosides. The reaction rate of glucose (an energy saccharide) was slow, and it easily produced the Amadori compounds. The study of the reactivity of aromatic amines with saccharides, the measurement of the retention of monosaccharides on amino phase in chromatography, and the synthesis of N-glycosides for the determination of their structures will provide useful information about selective glycosylation for the modification of drug candidates to improve their water solubility.

N-Tolylglycosylamines were synthesized from o-, m-, and p-toluidines and aldoses (D-glucose, D-galactose, D-mannose, L-rhamnose, D-xylose, and L-arabinose). The anomeric and isomeric compositions of the synthesized products were established using 13
