To prepare the cyclic product other than six-membered rings from intramolecular aldol addition of 2,6-heptanedione Concept introduction: Aldol reaction is an addition reaction of aldehydes and ketones . Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named β -hydroxy aldehyde if two aldehydes combine and β -hydroxy ketone if two ketones combine. If a compound has two functional groups that can react with each other, an intramolecular reaction readily occurs if the reaction leads to occur five or six-membered rings.
