Carbonyl Condensation Reactions (Aldol, Claisen, Dieckmann, Robinson)

Problem # 750

Let's work through a Robinson annulation.

Work backwords to determine the starting materials needed to produce each intermediate below, then show a mechanism for the overall reaction.

Problem # 747

Show a combination of enolate (nucleophile) and electrophile that can produce each compound below.

Remember that all enolates come from carbonyls.
