| Description: These reactions are initiated by deprotonation of the weakly acidic hydrogen to give a resonance-stabilized enolate ion (top). In an aldol condensation (left side), the enolate adds to an aldehyde or ketone, yielding a b-hydroxy carbonyl product. In a Claisen condensation (right side), the enolate adds to an ester, yielding a b-keto product.
