A process comprising the following steps: a-i) treating a polyunsaturated ester with a base in a solvent of lower alcohol and water to form the corresponding polyunsaturated acid; a-ii) treating the product from step a-i), especially the crude product, with a halolactonization agent in the solvent of lower alcohol and water, to form the corresponding polyunsaturated halolactone; and a-iii) treating the product from step a-ii), especially the crude product, with a reagent in the solvent of lower alcohol and water to convert the polyunsaturated halolactone to the corresponding polyunsaturated epoxide lower alkyl ester.
