The present invention relates to novel fragrance compounds of general formula (I) which exhibit a Sandalwood-like fragrance and which are derivable from campholenic aldehyde derivates according to general formula (II). Furthermore, the present invention discloses compositions comprising one or more of the inventive fragrance compounds. The invention also relates to the use of such compounds or fragrance compositions comprising one or more of the compounds according to the invention as an odorant or or improving the fixation of a fragrance compound or a fragrance composition. Furthermore, the present invention refers to the use of such compounds or compositions for the preparation of a perfumed products as well as perfumed products as such.

A γ-caprolactone precursor-aroma compound and a preparation method and uses thereof are disclosed. The preparation method specifically includes: dissolving γ-caprolactone in a sufficient amount of a solvent, adding an alkali at −78° C. to 0° C., stirring the resulting mixture to allow a reaction for 20 min or more, adding 2-acetylpyridine, further stirring at −78° C. to 0° C. to allow a reaction for 30 min or more, quenching the reaction, and finally subjecting the resulting reaction system to post-treatment, separation, and purification to obtain the target lactone precursor-aroma compound. The precursor-aroma compound of the present disclosure has stable properties in a normal temperature environment, can uniformly release an aroma under heating, increase and enrich the types of lactone fragrances, broaden an application range of lactone fragrances and acylpyridines, and overcome the defects of lactone and acylpyridine themselves, such as high volatility, small threshold, strong smell, and easy loss during processing.

A compound represented by the formula 1 ##STR00001##
wherein R.sub.1 is H, or when R.sub.2 and R.sub.3 is H, then R.sub.1 is CHR.sub.5CHR.sub.6CHO, CR.sub.5═CR.sub.6CHO or C(CH.sub.3)CHO, wherein R.sub.5, R.sub.6 each independently may represent H or methyl; R.sub.2 is H, or when R.sub.1 and R.sub.3 is H, then R.sub.2 is CHR.sub.5CHR.sub.6CHO, CR.sub.5═CR.sub.6CHO or C(CH.sub.3)CHO, wherein R.sub.5, R.sub.6 each independently may represent H or methyl; R.sub.3 is H, or when R.sub.1 and R.sub.2 is H, then R.sub.3 is CHR.sub.5CHR.sub.6CHO, CR.sub.5═CR.sub.6CHO or C(CH.sub.3)CHO, wherein R.sub.5, R.sub.6 each independently may represent H or methyl; and R.sub.4 is methyl or a branched or linear, saturated or unsaturated, unsubstituted or substituted (optionally with cyclopropyl groups), C.sub.2-C.sub.7 alkyl or alkenyl residue, preferentially isobutyl, isoamyl.
Said compounds are useful as perfume ingredients in personal care and household care products.

The present invention primarily concerns the use of compounds of the following formula (I) ##STR00001##
wherein X represents an oxygen atom, a —CHO, an —OH, or a —CH.sub.2OH group, a single bond or a double bond is present at the respective location of one of the dotted lines, at least one double bond is present when X is an OH group, and the 3-isopentyl or 3-isopent-2-enyl residue is connected to the ring in the ortho, meta, or para position to the X group, as perfuming and/or flavouring agents. The invention further relates to fragrance and flavour compositions containing one or more of these compounds, perfumed or flavoured articles comprising one or more of these compounds and corresponding processes for imparting, modifying and/or enhancing certain odour notes.
