Mixture of 1-(2-propenyl)-3-(4-methyl-3-pentenyl)-.sup.3 - cyclohexene-1-carboxaldehyde and 1-(2-propenyl)-4-(4-methyl-3-pentenyl)-. DELTA..sup.3 -cyclohexene-1-carboxaldehyde and process for producing same

摘要

Described are the compounds 1-(2-propenyl-3-(4-methyl-3- pentenyl)-. DELTA..sup.3 -cyclohexene-1-carboxaldehyde and 1-(2-propenyl)- 4-(4-methyl- 3-pentenyl)-.sup.3 -cyclohexene-1-carboxaldehyde; and a process for preparing same by means of reacting an allylic halide with a mixture of 3 and 4-(4-methyl-3-pentenyl)-.sup.3 -cyclohexene-1- carboxaldehyde using a phase transfer agent in a two phase system according to the reaction: ##STR1## wherein the carboxaldehyde moiety is bonded to the alpha-carbon atom or the beta-carbon atom, X is chloro or bromo and M is alkali metal, processes for adding such 1-(2-propenyl)-(4- methyl-3-pentenyl)-.sup.3 -cyclohexene-1-carboxaldehydes to consumable materials whereby:PP(I) In foodstuffs and medicinal products, sweet, fatty, cocoa butter-like, green/grassy, dairy, diacetyl-like, apricot-like and carrot-like aroma characteristics and fatty, cocoa butter-like, green/grassy, dairy-like, diacetyl-like, peach and coconut flavor characteristics are augmented or enhanced;P P(II( In perfumes and perfumed articles, sweet, fruity, lavender notes with citrus, floral and balsam nuances are imparted, augmented and/or enhanced; andPP(III) In tobaccos and tobacco flavor and aroma imparting or enhancing compositions, cocoa liquor-like, sweet-rich and creamy oily notes are imparted, prior to, and, on smoking and flavor compositions and perfume compositions containing the 1-(2- propenyl)-(4-methyl-3-pentenyl)-.sup.3 -cyclohexene-1- carboxaldehydes.
