Abstract: Described is a process comprising adding to homogenized or reconstituted tobacco (for subsequent incorporation into smoking articles along with tobacco blend) an amount sufficient to alter the flavor or aroma of the ultimate tobacco mixture of tricyclene-9-butenone (1,7-dimethyl-7(1-pent-2-en-4-onyl) nortricyclene) having the structure: ##SPC1##

Abstract: Methods are described for adding 2-methyl-4-pentenoic acid and/or C.sub.2 -C.sub.6 alkyl esters thereof to foodstuffs, chewing gums or medicinal products in order to impart sweet, fruity, strawberry, winey-cognac, pineapple-like, pear, green and/or apple-like aromas and tastes; with cooked strawberry jam undertones to said foodstuffs, chewing gums or medicinal products.

Abstract: Methods are described for adding the novel compounds, isobutyl and n-hexyl esters of 2-methyl-4-pentenoic acid to foodstuffs, chewing gums or medicinal products in order to impart sweet, fruity, strawberry, pineapple-like, pear and/or green aromas and tastes.

Abstract: Processes and compositions are described for the use in foodstuff flavor and aroma, tobacco flavor and aroma and perfume aroma augmenting, modifying, altering and enhancing compositions and as foodstuff, chewing gum, toothpaste, medicinal products, tobacco, perfume and perfumed article aroma imparting materials of mixtures of (i) 2,2,6-trimethyl-1-cyclohexen-1-ylacetaldehyde (hereinafter referred to as "beta-cyclohomocitral") and (ii) 2,6,6-trimethyl-crotonyl-1,3-cyclohexadiene having the structure: ##SPC1##Hereinafter referred to as "damascenone". Addition of mixtures beta-cyclohomocitral and damascenone is indicated to produce:A. In food flavorings, a fruity, rosey, woody, tea aroma and a woody-tea, fruity-tobacco flavor;B. In tobacco, a sweet, floral, fruity, earthy, green aroma prior to smoking and a sweet, rich, tobacco-like smoke aroma augmenting effect with woody flavoring characteristics in the mainstream on smoking; andC. In perfumes, rosey, woody, camphoraceous, green and earthy notes.

Abstract: The flavor of a foodstuff is altered, modified or enhanced by the addition thereto of one of the four compounds, the structure of which is one of the configurations of 3((2-mercapto-1-methylpropyl) thio)-2-butanol represented by the structures: ##SPC1##Each of these configurations produced by the process described herein, of reacting either a cis or trans 2,3 butane episulfide with an "erythro" or "threo" 2-hydroxy-3-mercapto butane, represented by the structures: ##SPC2##

Abstract: Processes and compositions are described for the use in foodstuff flavor and aroma and as foodstuff aroma imparting materials of 2,2,6-trimethyl-1-cyclohexen-1-ylacetaldehyde.

Abstract: 3-Furyl beta-chalcogenalkyl sulfides having the structure: ##SPC1##Wherein X is a chalcogen selected from the group consisting of oxygen and sulfur; R.sub.2 and R.sub.3 are each selected from the group consisting of methyl and hydrogen, at least one of R.sub.2 or R.sub.3 being methyl; and R.sub.4 and R.sub.5, taken separately, are each methyl, or R.sub.4 and R.sub.

Abstract: Methods for producing cis-alkyl-2-methyl-3-pentenoates and isomeric mixtures containing high proportions (greater than 50%) of cis C.sub.2 -C.sub.6 alkyl-2-methyl-3-pentenoates.

Abstract: A method for producing mixtures containing greater than 50% cis 2-methyl-3-pentenoic acid comprising first reacting methyl acetylene with a methyl magnesium halide to form a methylacetylene magnesium halide Grignard reagent; then reacting the methyl acetylene magnesium halide Grignard reagent with acetaldehyde to form a 3-pentyn-2-ol magnesium halide salt; then hydrolyzing the magnesium halide salt to form 3-pentyn-2-ol; then halogenating the 3-pentyn-2-ol to form a 4-halo-2-pentyne; then reacting magnesium with the 4-halo-2-pentyne to produce a 4-magnesium halo-2-pentyne Grignard reagent; then reacting the 4-magnesium halo-2-pentyne Grignard reagent with carbon dioxide to form a magnesium halo-carboxylate salt mixture of compounds having the structures: ##EQU1## (wherein X is halogen); then hydrolyzing the magnesium halo-carboxylate salt mixture to form a mixture of carboxylic acids having the structures: ##EQU2## then hydrogenating the aforementioned mixture of carboxylic acids to form a mixture containing
