An efficient synthesis of 4-oxo-2-alkenoic acids is achieved by the reaction of 2-alkylfurans with sodium chlorite in acidic aqueous solution. The method is applicable to the total synthesis of biologically active phospholipids containing this functional array. The oxidation procedure also converts 2,5-dialkyl furans to α,β-unsaturated-y-diketones in good yields.
An excellent fragrance compound having high palatability. A 3- (3-hexenyl)-2-cyclopentenone represented by a general formula (1)
(wherein wavy line represents a double bond cis-form and/or trans-form) is used as an active ingredient of scent and mixed in a small amount with fragrance compositions, cis-jasmone and/or various materials to be scented. Since the above compound has a characteristic fragrance quality and high palatability, it is markedly useful as a scenting component of various fragrances and cosmetics, sanitation materials and the like.
