Mannich Bases: An Important Pharmacophore in Present Scenario
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. The reaction is named after chemist Carl Mannich. The Mannich reaction is an example of nucleophilic addition of an amine to a carbonyl group followed by dehydration to the Schiff base.
The Mannich reaction has been widely used to effectively construct C—N and C—C bonds in organic synthesis. This review focuses on selected applications of the intramolecular Mannich reaction as a key step in the total synthesis of natural products — The organization of the synthetic applications is based on the structure of newly-formed skeletons using the intramolecular Mannich reaction, which include aza-fused rings and aza-bridged rings.
