Treatment of methyl β-L-arabopyranoside under hydrogenolytic conditions with copper chromium oxide catalyst induces extensive isomerization. Products formed include glycosides of D-ribose, D-xylose, D-lyxose, and L-lyxose which together represent about an 80–90% conversion of starting material. Isolation of these compounds shows that carbons 2, 3, and 4 undergo isomerization, but no evidence has been obtained of anomerization. These findings possibly explain the formation of an optically inactive mixture of cis- and trans-tetrahydropyran-3,4-diol under slightly more drastic reaction conditions.

A compound formed during the hydrogenolysis of sucrose in ethanol or dioxane at 180 °C, in the presence of copper chromium oxide catalyst, has been characterized as 2,6-anhydro-β-D-fructofuranose (2,5-anhydro-α-D-fructopyranose), a new type of anhydro-ketose. Ethyl α- and β-D-fructofuranosides are also produced when the hydrogenolysis reaction is carried out in ethanol, and various derivatives of these anomeric ketosides have been prepared.
