    Abstract: Cyclohexane-1,3-dione derivatives of the formula I where R1 is alkyl of from 2 to 4 carbon atoms, R2 is alkyl, unsubstituted or halogen-substituted alkenyl, or alkynyl, each of from 2 to 5 carbon atoms, R3 is a saturated or unsaturated hydrocarbon radical of up to 4 carbon atoms which is unsubstituted or substituted by 1 to 3 hydrocarbon radicals of a total of up to 8 carbon atoms, by aryl of from 6 to 10 carbon atoms, or by benzyl, R4 is, when R3 is unsaturated or olefinically or aromatically substituted, alkyl of from 1 to 6 carbon atoms, R4 is further unsubstituted or halogen-substituted alkenyl of from 2 to 6 carbon atoms, alkynyl of from 2 to 6 carbon atoms, naphthyl, arylalkyl or arylalkenyl, where aryl is of from 6 to 10 carbon atoms and is unsubstituted or substituted by alkyl or alkoxy, each of from 1 to 3 carbon atoms, or by halogen, and where alkyl or alkenyl is of from 2 to 3 carbon atoms, at least 2 of which being between aryl and sulfur, Z is H, CN, CH3, methoxycarbonyl or ethoxycarbonyl, and n is 0,1 or 2, and salts thereof.

    Abstract: Substituted 5-formyl-1,3-dioxepans of the general formula I (I) where R1 is a straight-chain or branched alkyl radical of 1 to 10 carbon atoms which may furthermore contain oxygen in the form of an ether group, or a 5-membered to 8-membered ring which is unsubstituted or substituted by alkyl groups and/or an alkylene group, has up to 10 carbon atoms and may furthermore contain oxygen in the form of an ether group, R2 is hydrogen, or R1 and R2 together form an alkylene radical of 4 to 10 carbon atoms which is unsubstituted or substituted by alkyl or alkoxy and may furthermore contain oxygen in the form of an ether group, and R3, R4, R5 and R6 are each hydrogen or methyl, and the total number of carbon atoms is not more than 25, their preparation and their use as scents. Particularly interesting compounds are 2-tert-butyl-5-formyl-1,3-dioxepan, 2-isopropyl-5-formyl-1,3-dioxepan, 2-pentyl-4,7-dimethyl-5-formyl-1,3-dioxepan, 2-(2,4,4-trimethylpentyl)-5-formyl-1,3-dioxepan, 9-formyl-7,12-dioxaspiro[5,6]dodecane and 2,4,4,7,7-pentamethyl-5-formyl-1,3-dioxepan.
