PURPOSE: To obtain a new type carbonate or a dithiocarbonate compound available from a fish oil highly unsaturated fatty acid, etc., conventionally having no suitable use, etc.
CONSTITUTION: This heterocyclic compound is represented by the formula R1 COOR2 (R1 denotes a hydrocarbon chain having 4-6 epoxy groups; R2 denotes H or an alkyl group comprising 1-8 carbon atoms or an aryl group which may have a substituent group), prepared by carbonating or thiocarbonating ≥2 epoxy groups in the molecule of an epoxy compound derived from a highly unsaturated fatty acid or its derivative and contains a five-membered ring having two oxygen atoms or one oxygen atom and one sulfur atom as hetero-atoms. The heterocyclic compound is a compound obtained by carbonating or dithiocarbonating four or more or all the epoxy groups in the molecule of the epoxy compound which is a raw material or a mixture of the compound having all the carbonated or dithiocarbonated epoxy groups in the molecule with a compound having the residual epoxy groups.
