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 B-keto ester, an enamine, or a 3-diketone) and an o.B-unsaturated ketone acceptor. The product is a substituted 2-cyclohexenone derivative, Draw the structures of the nucleophile cyclic ketone and the a,p-unsaturated ketone acceptor that were combined in a Robinson annulation to give the following product: 89 a la 998) go upg Out!
