1 410 9 2 14 34 4 10 1222 Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: wherein Ris C-Cstraight chain alkyl or C8-alkenyl; and wherein Ris C-Calkyl, C-C2-alkenyl, C3-alkenyl or Cnon-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-CH-CH(OR) (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.
