Abstract
AbstractMono‐ and diesters of fatty acids of peracetylated α‐d‐glucopyranose were prepared by chemical interesterification. Substituent‐induced chemical shift effects on the carbonyl carbons rather than the ring carbons and proton atoms unambiguosly show the fatty acyl substituents to be at C1 in the monosubstituted, and at C1 and C6 in the disubstituted products. 1H nuclear magnetic resonance (NMR) integration data before and after interesterification complemented 13C chemical shift data in verifying the molecular structures. Empirical data from classical 1H and 13C NMR experiments thus provide a simple self‐contained method for determining the number and position of fatty acyl substituents, and the anomeric compositions of peracetylated glucose fatty esters.
