Reaction Steps
A solution of dimethyl cyclohex-2-ene-1,4-dicarboxylate and dimethyl cyclohex-1-ene-1,4-dicarboxylate is hydrogenated under balloon pressure at room temperature over Pd/C catalyst. If methylene chloride is used as the solvent, primarily the 2-ene tautomer is reduced, whereas most of the 1-ene tautomer remains unreacted. If ethanol is used as the solvent both tautomers are reduced.
