Abstract
The present invention relates to novel compounds useful as fragrance materials which have the structure ##STR1## wherein the dashed line may be either a carbon-carbon single bond or a carbon-carbon double bond; R.sub.1, R.sub.2 and R.sub.3 are each the same or different and each represents hydrogen or methyl; and X is halogen. The invention also provides methods of preparing these compounds from readily available cyclohexene derivatives and fragrance compositions which include the compounds.
Claims3
A method of preparing a compound having the structure:
- ##STR14## wherein the dashed line may be either a carbon-carbon single bond or a carbon-carbon double bond;
- each of R.sub.1, R.sub.2, and R.sub.3 may be hydrogen or a methol group;
- and X is a halogen, which comprises reacting a substituted cyclohexane derivative having the structure:
- ##STR15## wherein the dashed line, R.sub.1, R.sub.2, and R.sub.3 are as above, with a hypohalous acid having the formula HO--X, wherein X is a halogen.
