The mechanism for the last step in the Kiliani-Fisher synthesis is to be drawn. Concept Introduction: In Kiliani-Fisher synthesis, hydrogen cyanide attacks the carbonyl group. The carbonyl carbon is converted to an asymmetric center. The C ≡ N bond is reduced to an imine which is partially deactivated by palladium catalyst to prevent the reduction of imine to an amine . The two imines are hydrolyzed to two aldoses.
