The structure of the intermediate A , dimedone and curved arrow mechanism for compound B formation are to be stated. Concept introduction: In Claisen condensation reaction two esters or one ester and a carbonyl compound react together to form β ketoester and β -diketone compound in the presence of a base. Michael addition reaction is a nucleophilic addition reaction of an anion to α , β -unsaturated carbonyl compound and results in the formation of conjugate addition product. When ester undergoes basic hydrolysis, it results in the formation of carboxylate salt and an alcohol which is the reversible step of ester formation.
