标 题 :Synthesis of 3-carbomethoxy-4,5-dimethylthiophene

摘要:Fungicides having thiophene rings may be made from the intermediate compound 3-carbomethoxy-4,5-dimethylthiophene. That compound, and related compounds, may be produced by reacting an alpha mercaptoketone, e.g., 3-mercapto-2-butanone, with an acrylate, e.g., methyl-3-methoxy acrylate, in the presence of an alkoxide base, e.g., NaOMe, to form the substituted tetrahydrothiophene, followed by conversion to the aromatic thiophene with an acid treatment. The substituted tetrahydrothiophene is a novel compound.

摘要: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.
