The use of various novel oxime ethers are described as fragrance chemicals. These chemicals are suitable for use in creating fragrance, and scents in items such as perfumes, colognes and personal care products is disclosed.

Oxime methyl ethers

The present invention is directed to novel compounds of the general formula  wherein R and Rindependently represent a hydrogen or a straight, branched or cyclic hydrocarbon moiety consisting of less than 15, preferably less than 10, most preferably less than 4 carbon atoms and containing single and/or double bonds. Another embodiment of the invention is a method for enhancing a perfume composition by incorporating an olfactory acceptable amount of the compound provided above.

1-phenyl-spiro[2.5]octane-1-carbonitrile analogues their use in fragrance formulations

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&#x2013;Cstraight chain alkyl or C8-alkenyl; and wherein Ris C&#x2013;Calkyl, C&#x2013;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&#x2014;CH&#x2014;CH(OR)(ii) then carrying out a thermal decomposition reaction at pH&#x3c;7 and then (iii) fractionally distilling the resulting reaction product to provide the enol ether.

Acyclic enol ethers, isomers thereof, organoleptic uses thereof and processes for preparing same

The novel compound, cyclohexanbutanol, 4-(hydroxymethyl)-alpha, alpha-dimethyl- having the structure:and the use of the compound in creating fragrances, and scents in items such as perfumes, colognes and personal care products is disclosed.
