You can try with triose-phosphate isomerase, an enzyme (EC 5.3.1.1) that catalyzes the reversible interconversion of the triose phosphate isomers dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate.
Thank you for the responds Sir. We need to convert eugenol to isoeugenol without using RhCl3. I just though that using enzyme as catalyst would be the solution. Is there any solution... Thank you so much
