Conan · Answer 1

cyclic β keto ester

Explanation:

The 1,7-diester CH3O2CCH2CH2CH (CH3) CH2CH2CO2CH3 undergoes Dieckmann condensation which is when sodium methoxide (a base) catalyzed intermolecular condensation of the diester into a cyclic β keto ester. The 1,6 diesters yields five member-ed cyclic β-keto esters while 1,7 diesters yields six member-ed cyclic β-keto ester
