The compound shown below is the product of a Claisen condensation or a Dieckmann condensation. Draw structural formulas for the ester and enolate ion reactants. Remember that a Dieckmann condensation is intramolecular and therefore the enolate ion and the ester are part of the same reactant.
Draw the enolate ion in its carbanion form.
Assume all esters to be used are ethyl esters.
Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
Separate multiple reactants using the + sign from the drop-down menu.
