摘要：
The invention relates to the process for the preparation of new derivatives of amino-ascorbic acid, their acid and alkali salts, processes for preparation and action.According to this invention derivatives of amino-ascorbic acid are prepared by three types of reactions: 1. reductive alkylation of amino-ascorbic acid; 2. alkylation of primary and secondary amines with halogen-ascorbic acid and 3. acylation of amino-ascorbic acid.
