Abstract
Described is a genus of E2,E4,Z8-undecatrienoic acid derivatives defined according to the structure:wherein Z represents —OR″ or —NRR′ with the provisos that when Z is —OR″, R″ is hydrogen, C1–C6 straight chain or branched-chain alkyl or C3–C6 straight chain or branched-chain alkenyl; and when Z is —NRR′, R represents, in the alternative, hydrogen, methyl or ethyl and R′ represents methyl, ethyl, n-propyl, cyclopropyl, isopropyl, n-butyl, sec-butyl, isobutyl, 2-methylbutyl, cyclobutyl,cyclopentyl or allyl. The E2,E4,Z8-undecatrienoic acid derivatives are useful in imparting, augmenting and/or enhancing flavors, aromas and somatosensory effects in or to consumable materials such as foods, beverages, skin care products, oral care products, medicinal products and the like. Also described is a synthesis process for producing such derivatives.
