The Stork reaction is a condensation reaction between an enamine donor and an a,B-unsaturated carbonyl acceptor. The overall reaction consists of a three-step sequence of 1. formation of an enamine from a ketone, 2. Michael addition to an a,B-unsaturated carbonyl compound, and 3. hydrolysis of the enamine in dilute acid to regenerate the ketone.

СО cat. H + NH2CH3 + H2CO2C CO2CH3 CO CHE Cocaine has been prepared by a sequence beginning with a Mannich reaction between dimethyl acetonedicarboxylate, methylamine, and butanedial. The mechanism involves the following steps: 1. Following initial protonation of the carbonyl oxygen, nucleophilic attack by the amine forms carbinolamine 1; 2. Proton transfer and elimination of water forms iminium ion 2; he enol form of the dicarboxylate ester attacks the iminium ion to form adduct 3; 4. Adduct 3 tautomerizes...
