Abstract
A process for the preparation of aldobionamides directly from an aldobionic acid starting material, in which an aldobionic acid is reacted by removing water by azeotropic distillation to obtain an aldobionolactone. The aldobionolactone can then be reacted with amines without further purification or isolation steps to obtain the aldobionamide.
