FTP name this reaction between an enolate and an alpha, beta-unsaturated carbonyl compound, noted for its conjugate 1,4-addition product.
In this reaction, unsaturated aldehydes, esters, nitriles, and amides are common acceptor components, while malonic ester and the product of a Claisen condensation are common donors.  The base catalyst removes a proton from the donor, commonly a beta-keto ester, which then must be able to form a stable enolate ion.  Another enolate is formed after the newly created nucleophile attacks the carbon-carbon double bond of the acceptor, which then abstracts a proton from the solvent to complete the reaction.
