Oxidative degradation of lactose hydrazones to galarose

J. Turjan, V. Patoprsty, M. Petrusova, and L. Petrus

Abstract: Oxidative degradation of lactose 2,5-dichlorophenylhydrazone to galarose and 2-(2,5-dichlorophenyl)hydrazinecarbaldehyde with hydrogen peroxide was found to give the best results in a weakly acidic medium under catalysis of ammonium heptamolybdate. Of fourteen lactose hydrazones evaluated, the best yields of galarose were obtained with 2,4-, 2,5-, and 3,5-dichlorophenylhydrazones.
