Abstract: 3-Oximino-4-oxo-2,5-dimethyltetrahydrofuran of the formula (1) is prepared by oximating 3-carboxy-4-oxo-2,5-dimethyltetrahydrofuran. The oximation is effected using aqueous nitrous acid, nitrous acid esters or nitrosyl chloride at temperatures from -50 to +50 DEG C. The compound which is obtained can be converted into 4-oxo-3-hydroxy-2,5-dimethyl-4,5-dihydrofuran by oxidation, hydrolysis with an acid or reoximation and subsequent rearrangement of the resulting vicinal dioxo compound.

Abstract: New 1-acyl- and 1-hydroxymethyl-cyclododecanes and -cyclododecenes. The new 1-acyl-cyclododecenes and -cyclododecanes are obtained by a Rupe or Meyer-Schuster rearrangement, with or without subsequent hydrogenation in the presence of Ni, Pd and Pt catalysts. The 1-acyl-cyclododecenes and -cyclododecanes are valuable scents of the basic type of the sought-after macrocyclic musk scents. Furthermore, they are used for the manufacture of numerous other new 1-substituted or 1-and 2-substituted cyclododecenes and cyclododecanes having good scent characteristics.

Abstract: New substd. 1-alkeninyl-cyclohexenes have the general formula (I): (in which R1-4 are H or CH3; R5 and R6 are H or satd. or olefinically unsaturated aliphatic 1-6C hydrocarbon gps., pref. H, CH3 or C2H5; alternatively R5 and R6 form together a 3-6C alkylene bridge opt. alkyl substd.; pref. R5 and R6 do not contain together more than 6C). (I) can be produced by dehydrating the corresp. substd. 1-alkeninyl-cyclohexanols or 1-cycloalkanoyl-alkynols. (I) have strong spicy, or woody-herby, or flowery aroma. They can be used in perfume compsns., in cosmetics, etc. They also can be used to mask unpleasant odours.

Abstract: Aromatic amines, in particular substituted amines, are obtained from corresponding alicyclic alcohols or ketones, in one step, by amination and dehydrogenation with ammonia in the presence of hydrogen and of a palladium catalyst which also contains zinc or cadmium.

Abstract: 3-Substd. 2,5-dimethoxytetrahydrofurans of formula (I) are new, (where R1 is H or 1-4C alkyl, pref. Me or Et, R2 is H, Ph or opt. olefinically unsatd. 1-11C aliphatic, aliphatic-cycloaliphatic or cycloaliphatic gp. opt. contg. O in the form of an alkoxy, carbonyl, alkoxycarbonyl or acetal gp., or R1 and R2 together form an opt. alkyl-substd. 4-8C alkylene gp.). (I) are intermediates in the prepn. of the terpenoids dendrolasin and torreyal which are perfumes. Dendrosalin is also an insecticide effective against ants. Some (I) are themselves perfumes.

Abstract: New substd. 1-alkeninyl-cyclohexanols are of formula (I) (in which R1-4 denote H or CH3; R5 and R6 denote H or satd. or olefinically unsatd. aliphatic 1-6C hydrocarbon gps. which do not contain any heteroatoms; alternatively R5 and R6 form together a 3-5C alkylene bridge; pref. R5 and R6 do not contain together more than 6C). The cpds. have a pleasant coniferous wood-herb scent and can be used in perfume compsns. or for flavouring industrial products. They can also be converted by acid-catalysed rearrangement into the valuable beta-damascones used in perfumery. Cpds. can be produced by reacting together a cyclohexanone (II) and an enin (III), or its alkali salt, in an inert solvent in the presence of a strongly basic condensation agent.

Abstract: New 7-alkoxy-6-methyl-5-hepten-2-ones RO-CH2-CMe=CH-CH2-CH2-CMeO (I) (where R is Me, Et, n- or iso-C3H7), are perfurmes having fruity, green tones. (I) are also intermediates for 12-alkoxy-3,7,11-trimethyl-dodecatetraenes (IV), useful as perfumes and flavouring materials having an orange-fruity, green note. (I) are prepd. from alkoxyacetones RO-CH2-CO-CH3 (II) first vinylated, or ethynylated and partly hydrogenated. The 1-alkoxy-2-hydroxy-2-methyl-3-butenes obtd., of formula RO-CH2-C(OH)Me-CH=CH2 (III), are then converted to (I).
