4-hepten-2-yl salicylate and its use as fragrance ingredient

A compound of the formula ##STR1## used as an odorant and/or flavorant and organoleptic compositions employing same.

Organoleptic compositions

Methyl (E)-4,7-octadienoate �(E)-4,7-octadienoic acid methyl ester! (1), as well as odorant and/or flavorant compositions containing compound (1) as an organoleptic active substance and the manufacture of compound (1). ##STR1##

Organoleptic compound and composition

The invention concerns odorant and flavorant compositions which contain one or more compounds of the formula ##STR1## wherein R represents an alkyl group having from three to eight carbon atoms. The invention also concerns 5-methyl-6-pentyl-tetrahydro-.alpha.-pyrone (compound of formula I in which R represents pentyl) in the form of its cis-isomer, its trans-isomer or its cis/trans isomer mixture, and a process for its manufacture by a Bayer-Villiger oxidation of 2-pentyl-3-methyl-cyclopentan-1-one. As fields of use for these compounds there come into consideration, for example, perfume and flavoring compositions, foodstuffs, semi-luxury consumables and drinks.
