The reaction that shows the formation of the given compounds by taking 3 − pentanone as a starting reagent is to be determined. Concept Introduction: The γ-lactones are formed by the intramolecular cyclization of the carboxylic esters. Epoxides are the cyclic compounds which provide a route for the preparation of γ-lactones . The compounds containing carbonyl groups are attacked by these epoxides which cause the alkylation at the alpha position of the carbonyl compound.
