Abstract

The present invention is directed to novel fragrance compounds and their unexpected advantageous use in improving, enhancing or modifying a fragrance formulation through the addition of an olfactory acceptable amount of the compounds, wherein the compounds are represented by the following formula:

an isomer or a mixture of isomers thereof,
wherein one of R and R′ represents hydrogen with the other representing a C 1 -C 6 linear, branched, or cyclic alkyl, alkenyl, alkynyl or aromatic group; and
one of the dashed lines represents a carbon-carbon single bond with the other representing a carbon-carbon double bond.

First claim

What is claimed is:

1. A compound of formula:

an isomer or a mixture of isomers thereof,
wherein one of R and R′ represents hydrogen with the other representing a C 1 -C 6 linear, branched, or cyclic alkyl, alkenyl, alkynyl or aromatic group.

2. The compound of claim 1 , wherein the compound is a compound of formula:

an isomer or a mixture of isomers thereof,
wherein one of R 1 and R 2 represents hydrogen with the other representing a C 1 -C 6 linear, branched or cyclic alkyl group.

3. The compound of claim 2 , wherein the compound is selected from the group consisting of:
(E)-4-Ethylidene-2-methoxy-cyclohexanol;
(Z)-4-Ethylidene-2-methoxy-cyclohexanol;
(E)-5-Ethylidene-2-methoxy-cyclohexanol;
(Z)-5-Ethylidene-2-methoxy-cyclohexanol;
(E)-4-Ethylidene-2-ethoxy-cyclohexanol;
(Z)-4-Ethylidene-2-ethoxy-cyclohexanol;
(E)-5-Ethylidene-2-ethoxy-cyclohexanol;
(Z)-5-Ethylidene-2-ethoxy-cyclohexanol;
(E)-4-Ethylidene-2-propoxy-cyclohexanol;
(Z)-4-Ethylidene-2-propoxy-cyclohexanol;
(E)-5-Ethylidene-2-propoxy-cyclohexanol;
(Z)-5-Ethylidene-2-propoxy-cyclohexanol;
(E)-4-Ethylidene-2-isopropoxy-cyclohexanol;
(Z)-4-Ethylidene-2-isopropoxy-cyclohexanol;
(E)-5-Ethylidene-2-isopropoxy-cyclohexanol;
