The reaction of acetonides of α-hydroxycarboxylic acids with primary amines on heating provides a useful synthetic route to N-substituted α-hydroxycarboxamides. In general, formation of the α-hydroxycarboxamides is favored by the presence of only small substituents on the acetonide, by sufficient nucleophilicity of the amine, and by high-boiling aprotic solvents.
