From the decomposition products of D-glucuronolactone isonicotinoyl hydrazone (II) at room temperature, D-glucuronic acid isonicotinoyl hydrazone isonicotinoyl hydrazide (III) was isolated, which has been identified to produce when the water solution of (II) was heated. Furfralaldehyde isonicotinoyl hydrazone (IX) was also isolated from the reaction solution. (III) has been recognized to be produced from 1-deoxy-1-(2-isonicotinoylhydrazino)-β-D-glucopyranosiduronic acid (VII) and ethyl 1-deoxyisonicotinoylhydrazino)-β-D-glucopyranosiduronate (VIII).
As to the mechanism of production of (III), the reaction, one molecule of glucuronolactone was released from 2 molecules of (II), may be considered to be taken place in the similar reaction to disproportionation.
