Intramolecular aldol condensation : The aldol condensation also offer a convenient way to synthesize molecules with five and six membered ring.This can be done by an intramolecular aldol condensation using a dialdehyde, a keto aldehyde or a diketone as the substrate.The major product is formed by the attack of the enolate from the ketone side of the molecule that adds to the aldehyde group.The reason the aldehyde group undergoes addition preferentially may arise from the greater reactivity of aldehyde towards nucleophilic addition.In reaction of this type five membered rings from far more readily than seven membered rings and six membered rings are more favourable than four or eight membered rings when possible.
