Acyclic enol ethers, isomers thereof, organoleptic uses thereof and processes for preparing same
Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: wherein R 1 is C 4 –C 10 straight chain alkyl or C 9 8-alkenyl; and wherein R 2 is C 1 –C 4 alkyl, C 3 –C 4 2-alkenyl, C 4 3-alkenyl or C 10 non-allenic alkadienyl and uses thereof in imparting, augmenting or enhancing the aroma and/or taste of a consumable material such as a perfume composition, a cologne, a perfumed article such as a soap, cosmetic, hair preparation or detergent, a foodstuff, a chewing gum or an alcoholic or non-alcoholic beverage such as a carbonated beverage or fruit liquer. Also described is a process for synthesis of such enol ethers by means of (i) first forming an acetal having the structure: R 1 —CH 2 —CH(OR 2 ) 2 (ii) then carrying out a thermal decomposition reaction at pH<7 and then (iii) fractionally distilling the resulting reaction product to provide the enol ether.
