Abstract
The present invention relates to novel cyclopropane derivatives represented by Formula I: wherein R represents a hydrocarbon group containing 1-20 carbon atoms or an ester containing 1-20 carbon atoms; wherein R′ represents a C1-C6 acyclic carboxylic acid ester, a C4-C6 cyclic carboxylic acid ester or —OR″, and R″ is selected from the group consisting of H, a C1-C6 acyclic hydrocarbon group, a C3-C6 carbocyclic ring and a C4-C5 heterocyclic ring; and wherein the composition is selected from the group consisting of a flavor composition and a fragrance composition.
Claims20
A composition comprising an olfactory acceptable amount of a compound of Formula I:
- wherein R represents a hydrocarbon group containing 1-20 carbon atoms or an ester containing 1-20 carbon atoms;
- wherein R′represents a C1-C6 acyclic carboxylic acid ester, a C4-C6 cyclic carboxylic acid ester or —OR″, and R″ is selected from the group consisting of H, a C1-C6 acyclic hydrocarbon group, a C3-C6 carbocyclic ring and a C4-C5 heterocyclic ring;
- and
- wherein the composition is selected from the group consisting of a flavor composition and a fragrance composition.
A method of improving, enhancing or modifying a composition through the addition of an olfactory acceptable amount of a compound of Formula I:
- wherein R represents a hydrocarbon group containing 1-20 carbon atoms or an ester containing 1-20 carbon atoms;
- wherein R′ represents a C1-C6 acyclic carboxylic acid ester, a C4-C6 cyclic carboxylic acid ester or —OR″, and R″ is selected from the group consisting of H, a C1-C6 acyclic hydrocarbon group, a C3-C6 carbocyclic ring and a C4-C5 heterocyclic ring;
- and
- wherein the composition is selected from the group consisting of a flavor composition and a fragrance composition.
A compound selected from the group consisting of Formula II and Formula III;
- wherein R1, R2, R3 and R4 are each independently selected from the group consisting of H and CH3;
- wherein R′ represents a C1-C6 acyclic carboxylic acid ester, a C4-C6 cyclic carboxylic acid ester or —OR″, and R″ is selected from the group consisting of H, a C1-C6 acyclic hydrocarbon group, a C3-C6 carbocyclic ring and a C4-C5 heterocyclic ring;
- and
- wherein the dashed line represents a single or double bond.
