Interpretation Introduction

Interpretation:

The dicarbonyl precursor used for preparing the compound represented by the model in an intramolecular aldol reaction is to be identified.

Concept introduction:

In intramolecular aldol reaction rections dicarbonyl compounds react with a base to yield a cyclic product. In these reactions both the nucleophilic carbonyl anion donor and the electrophilic carbonyl acceptor are present in the same molecule. The mechanism is similar to intermolecular aldol condensation.

To identify:

The dicarbonyl precursor used for preparing the compound represented by the model in an intramolecular aldol reaction.
