Name Reaction Reisebecher

The Mannich reaction is an organic reaction used to convert a primary or secondary amine and a carbonyl compound to a β-amino carbonyl compound, also known as a Mannich base, using an acid or base catalyst. Reactions between aldimines and α-methylene carbonyls are also considered Mannich reactions because these imines form between amines and aldehydes. The reaction is named after chemist Carl Mannich.
