Abstract: Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: wherein R1 is C4–C10 straight chain alkyl or C9 8-alkenyl; and wherein R2 is C1–C4 alkyl, C3–C4 2-alkenyl, C4 3-alkenyl or C10 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: R1—CH2—CH(OR2)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.

Abstract: Described are bicyclic lactones, both fused ring lactones defined according to the generic structure: and spiro lactones defined according to the generic structure: uses thereof in augmenting, enhancing or imparting aromas in or to perfume compositions, perfumed articles, colognes and perfumed polymers; processes for preparing such bicyclic lactones and intermediates therefor. In the structure: Z is one of the moieties: one of R1 or R3 is methyl and the other is hydrogen; and R4, R5, R6, R7, R8 and R9 hydrogen or nonadjacent C1–C3 alkyl.

Abstract: The compound according to the formula set forth below and the use of the compound in creating fragrances, and scents in items such as perfumes, colognes and personal care products is disclosed.
