Abu T. Khan, Mohan Lal, Md. The Mannich reaction is an organic reaction which consists of an amino alkylation of an acidic proton placed next to a carbonyl functional group by formaldehyde and a primary or secondary amine or ammonia.

Highly diastereoselective addition of nitromethane anion to chiral α-amidoalkylphenyl sulfones. In summary, we have introduced a new type of intramolecular redox-Mannich reaction that is complementary to the classic Reinhoudt reaction in that it provides regioisomeric products differing only in the position of one methylene bridge.
