Abstract
Monoaminodeoxystarch (6) having 0.92 as the degree of substitution by amino group was prepared by p-toluenesulfonylation of soluble starch, followed by the reaction with sodium azide, O-aceylation to impart solubility, and the reduction with lithium aluminum hydride. 6-Amino-6-deoxy-D-glucose was found as a main product in the hydrolyzate of 6. Diaminated starch (12) having 1.60 as the degree of substitution by amino group was prepared by p-toluenesulfonylation, followed by the reaction with sodium azide, and the reduction with lithium aluminum hydride.
