Zusammenfassung:	NEW MATERIAL:A compound shown by the formula I (R is 1-6C alkyl; R1 is H, or 1-3C alkyl; when R is 1C alkyl, R1 is 2-4C alkyl, and when R is 2C alkyl or 4-6C alkyl, R1 is 1-3C alkyl). EXAMPLE:2-Ethyl-cis-3-pentenoic acid. USE:An imparter for providing fragrance and flavor having durability or a modifier. Having a main tone of fragrance and flavor like fruit or grass, showing a tone of fruit, green flower, etc. which may have fatty fragrance and flavor. PREPARATION:A trans-2-alkenoic acid shown by the formula II is isomerized in an organic solvent in the presence of both hexamethylphosphoric acid triamide and a basic organic alkali metal compound (e.g., methyllithium, etc.) at about -70-about -50 deg.C, to give a compound shown by the formula I easily.
