The selective reduction of 3,4-dicarbomethoxyquinoline by lithiumaluminium hydride at low temperature affords only the unexpected 3-formyl 4-carbomethoxy quinoline. The difficulty of reduction of the usually more reactive 4-ester group can be explained by a steric hindrance by the H5, peri proton on one side and by the 3-ester group on the other side.
