Glucosylamine with periodate

A recent paper by Kawashiro, the original of which is not available to the reviewers, gives details of the oxidation of N-m- and N-p-nitrophenyl-D-glucosylamines by periodic acid under the usual conditions. The degree of hydrolysis of the glucosylamines is less than 30 %, and exactly five moles of oxidant are consumed, with the production of the quantity of formic acid which would result from the similar oxidation of glucose. The reaction is given as follows.
