    • A process for producing one or more alkyl-2-methyl pentenoates having the generic structure: ##STR1## comprising the steps of: I. Contacting with hydrogen gas one or more alkyl-2-methyl-3,4-pentadienoates having the structure: ##STR2## in the presence of a hydrogenation catalyst which may be either of: A. Raney Nickel;B. Palladium on carbon; orC. Palladium on calcium carbonateAt a temperature from about 10.degree. C up to about 100.degree. C, a hydrogen pressure from about 5 psig up to about 80 psig, the concentration of said catalyst based on the weight of the starting material, the alkyl-2-methyl-3,4-pentadienoate, being from about 0.1% up to about 10%;Ii. Recovering at least 60% by weight of one or more alkyl-2-methyl-cis-3-pentenoates having the structure: ##STR3## wherein R is alkyl having up to 6 carbon atoms; optionally III. Separating the ingredients of the resulting chemical composition to obtain ethyl-2-methyl-cis-3-pentenoate; and/or, optionally,Iv. Forming one or more carboxylic acids by means of admixing the resulting chemical composition with a basic hydrolysis agent which may be either an aqueous solution of alkali metal hydroxide, or an alcohol solution of an alkali metal hydroxide; and, optionally,V. Re-esterifying the resulting carboxylic acid(s) by reacting said carboxylic acid(s) with an esterifying agent such as an alkanol in the presence of a protonic acid catalyst.The products produced are useful in altering the organoleptic characteristics (aroma and/or taste) of foodstuffs, foodstuff flavors, chewing gum, medicinal products, tobaccos, flavoring compositions for tobaccos, perfumes, perfume compositions and perfumed articles such as soaps, colognes, cosmetic powders and detergent powders and liquids.
