Abstract

The present invention relates to novel quinazoline compounds and their use in perfume compositions. The novel quinazoline compounds of the present invention are represented by the following formula:

an isomer or a mixture of isomers thereof,
wherein the broken line represents a single or double bond.

First claim

What is claimed is:

1. A compound, 6,6a,7,8,9,9a-hexahydro-7,7,8,9,9-pentamethyl-5H-cyclopenta[H]quinazoline.

2. A fragrance formulation containing an olfactory acceptable amount of 6,6a,7,8,9,9a-hexahydro-7,7,8,9,9-pentamethyl-5H-cyclopenta[H]quinazoline.

3. The fragrance formulation of claim 2 further comprising a product selected from the group consisting of a perfume, a cologne, toilet water, a cosmetic product, a personal care product, a fabric care product, a cleaning product, and an air freshener.

4. The fragrance formulation of claim 3 wherein the cleaning product is selected from the group consisting of a detergent, a dishwashing composition, a scrubbing compound, and a window cleaner.

5. The fragrance formulation of claim 2 , wherein the olfactory acceptable amount is from about 0.005 to about 50 weight percent of the fragrance formulation.

6. The fragrance formulation of claim 2 , wherein the olfactory acceptable amount is from about 0.5 to about 25 weight percent of the fragrance formulation.

7. The fragrance formulation of claim 2 , wherein the olfactory acceptable amount is from about 1 to about 10 weight percent of the fragrance formulation.

8. A method of improving, enhancing or modifying a fragrance formulation through the addition of an olfactory acceptable amount of 6,6a,7,8,9,9a-hexahydro-7,7,8,9,9-pentamethyl-5H-cyclopenta[H]quinazoline.

9. The method of claim 8 , wherein the olfactory acceptable amount is from about 0.005 to about 50 weight percent of the fragrance formulation.

10. The method of claim 8 , wherein the olfactory acceptable amount is from about 0.5 to about 25 weight percent of the fragrance formulation.

11. The method of claim 8 , wherein the olfactory acceptable amount is from about 1 to about 10 weight percent of the fragrance formulation.
