Described is a process for augmenting or enhancing the aroma and taste of a smoking tobacco comprising adding to said smoking tobacco an organoleptic property modifying quantity of a composition of matter comprising more than 50% trans,trans- DELTA -damascone and in addition a process for augmenting or enhancing the aroma and taste of a smoking tobacco comprising adding to said smoking tobacco in an organoleptic property modifying quantity a product produced according to the process of (i) reacting 1-alpha-acetyl-2-alpha,6,6-trimethyl-3-cyclohexene with strong base in aqueous ethanol at reflux thereby producing 1-alpha-acetyl-2-beta,6,6-trimethyl-3-cyclohexene; (ii) reacting the 1-alpha-acetyl-2-beta,6,6-trimethyl-3-cyclohexene with n-methyl aniline Grignard thereby forming a first organometallic compound; (iii) reacting said first organometallic compound with acetaldehyde thereby forming a second organometallic compound; (iv) reacting said second organometallic compound with acid in order to hydrolyze said second organometallic compound thereby forming a hydroxy ketone having the structure: <IMAGE> in admixture with other compounds; (v) dehydrating said hydroxy ketone in admixture with other compounds thereby forming a mixture having a major proportion of trans, trans- DELTA -damascone having the structure: <IMAGE> in admixture with cis, trans- DELTA -damascone having the structure: <IMAGE> and in admixture with other compounds; and in addition smoking tobacco products containing same. |
