The stepwise mechanism for the given Robinson annulation is to be drawn. Concept introduction: Robinson annulation is a combination of Michael addition and intramolecular aldol condensation reactions. It takes place between an α,β -unsaturated carbonyl compound and a carbonyl compound. The enolate formation takes place from carbonyl compound which attacks the α,β -unsaturated carbonyl compound to form 1 , 5 -dicarbonyl compound. This compound undergoes intramolecular aldol condensation which leads to the formation of a ring.
