Abstract
2-Amino-aldohexoses and acid addition salts thereof are manufactured by reacting a 1-amino-2-ketohexose with anhydrous liquid ammonia, hydrolysing the resulting 1-imino-compound and, if desired, converting the 2-amino-aldohexose so obtained into an acid addition salt. One or more of the hydroxyl groups of the starting materials may be acylated, e.g. acetylated. In the examples, D-glucosamine hydrochloride is prepared from 1-amino-1-desoxy-D-fructose acetic acid salt by either the action of liquid ammonia under pressure at 95-105 DEG C. or prolonged contact with liquid ammonia at room temperature, followed in either case by hydrolysis with dilute hydrochloric acid. Specifications 832,080 and 833,263 are referred to.
