Disclosed are oxa macrocyclic ketones of formula (I) possessing musky, powdery, nitro musk odor characteristics.

The invention is in the field of fragrances and relates to novel oxa-macrocyclic fragrance compounds according to general formula (I) with a musk-based note and improved biological degradability and further with improved chemical stabilities. The invention also relates to methods for preparing these compounds. Furthermore, the present invention also relates to fragrance compositions comprising one or more of the inventive compounds. Moreover, the invention relates to the use of these compounds or fragrance compositions as an odorant or for improving the fixation of a fragrance compound or a fragrance composition as well as for the preparation of a perfumed product. In addition, the present invention thus also refers to the use of said compounds or compositions for the preparation of a perfumed products as well as perfumed products as such.

The present invention relates to compounds of the formula (I) and use thereof as fragrance. In a further aspect the present invention relates to compositions and fragrance mixtures containing compounds of the formula (I) and the products perfumed with these compositions and fragrance mixtures. Further, the present invention relates to a method for intensifying an odor or several odors selected from the group consisting of fruity, floral, spicy, woody, musk and ambrette and a method for endowing hair or textile fibers with one, several or all of the notes selected from the group consisting of fruity, floral, spicy, woody, musk and ambrette with use of one or more compounds of the formula (I). ##STR00001##

The present invention relates to the use of compositions comprising 4-isopropyl-1-methyl-7-oxabicyclo[2.2.1]heptan-2-ol or specific esters or ethers thereof and 3-isopropyl-6-methyl-cyclohex-2-en-1-one, or of 4-isopropyl-1-methyl-7-oxabic yclo[2.2.1]heptan-2-ol or specific esters or ethers thereof as aroma chemicals or for modifying and/or enhancing the aroma of a composition. The invention relates moreover to compositions comprising 4-isopropyl-1-methyl-7-oxabicyclo[2.2.1]heptan-2-ol or specific esters or ethers thereof and 3-isopropyl-6-methyl-cyclohex-2-en-1-one, to specific compositions comprising 4-isopropyl-1-methyl-7-oxabicyclo[2.2.1]heptan-2-ol, and to specific esters or ethers of 4-isopropyl-1-methyl-7-oxabicyclo[2.2.1]heptan-2-ol.
