The Robinson annulation is a combination of two carbonyl coupling reactions, the Michael reaction and the intramolecular aldol condensation. The most common partners in the reaction are a nucleophilic donor (such as a cyclic ketone, a β-keto ester, an enamine, or a β-diketone) and an α,β-unsaturated ketone acceptor. The product is a substituted 2-cyclohexenone derivative.

Draw the structures of the nucleophilic β-diketone and the α,β-unsaturated ketone acceptor that were combined in a Robinson annulation to give the following product:

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
