A simple procedure for the preparation of stereoregular polyhydroxypolyamides, ie, head, tail hydroxylated nylons, derived from d-glucaric acid and alkylenediamines is described. Sodium d-glucarate 6, 3-lactone was made in two steps from monopotassium d-glucarate by way of d-glucaro-6, 3-lactone. Methanol insoluble salt of sodium 6-[N-(aminoalkyl)]-d- glucaramide monomer precursors were conveniently prepared by refluxing methanol ...
