Vedclass · Answer

(D) Jasmone is a cyclopentenone derivative. The synthesis of jasmone via an intramolecular aldol condensation involves a precursor that contains both a ketone and an aldehyde group (or two ketone groups) positioned such that cyclization forms a five-membered ring. The structure shown in option $D$ is $3-methyl-2-(cis-2-pentenyl)-2-cyclopenten-1-one$ (jasmone). The precursor for this reaction is $cis-8-undecene-2,5-dione$. Under basic conditions,the $\alpha$-carbon of the ketone group undergoes an intramolecular aldol condensation followed by dehydration to form the cyclopentenone ring system of jasmone. Therefore,the correct reactant is the one shown in option $D$.

Choose the reactant whose aldol reaction would give jasmone.
