Vedclass · Answer

(D) The hydrolysis of the given cyclic anhydride (Meldrum's acid derivative) initially leads to the formation of an unstable intermediate,which is a substituted malonic acid derivative. This intermediate undergoes decarboxylation upon heating to form a $\gamma$-hydroxy acid. The $\gamma$-hydroxy acid then undergoes intramolecular cyclization (lactonization) to form a five-membered lactone ring ($\gamma$-lactone) with a carboxylic acid substituent. The final product is a five-membered lactone ring with a $-CO_2H$ group attached.

Predict the product of hydrolysis of the above molecule.
