Task: Text Categorization
Input (English): [AR] In order to avoid hydrolysis of the initial reactant strong bases such as Lithium diisopropylamide must be used and final intermediate must be neutralized by an aqueous acid in order to obtain the final product. The classic version of this reaction has one enolizable reactant while a variation involving aryl aldehydes has this reaction's namesake appended with Schmidt. The Stobbe modification is specifically for the diethyl ester of succinic acid and a related reaction using alpha-halo esters is known as the Darzens reaction, while an intramolecular version of this reaction is known as the Dieckman Reaction, which readily creates five or six membered rings. For 10 points, name this eponymous condensation reaction involving esters or ketones conducted in the presence of sodium ethoxide to yield beta-ketoesters.
