The Mannich reaction of hydrazones originally limited to the
coupling of hydrazones with formaldehyde has been extended to a large
variety of aldehydes through appropriate selection of experimental
conditions; in conjunction with the Japp–Klingmann reaction, this
process provides an efficient synthetic tool for the formation of
carbon–carbon bonds.

The addition of alpha-ketohydrazones to 2-acetamidobenzaldehyde proceeds efficiently in the presence of N-benzylpiperazine to afford in good to high yields the expected Mannich adducts; these are easily converted to quinoline derivatives under acidic conditions in a new Azo-Friedlander reaction.
