Abstract: of formula (I) is new. It has interesting properties and is useful as an intermediate for the perfuming agent 4-oxo-3-hydroxy-2,5-dimethyl-4,5-dihydrofuran. The parent patent concerned the 1-6C alkyl esters of cpd. (I) and it may be prepd. from these by saponification under mild conditions using NaHCO3, Na2CO3, NaOH or KOH. Alternatively it may be prepd. by hydrogenolysis of the corresp. benzyl esters using Pd or Pt or C, CaCO3, SiO2 or Al2O3 carriers and is ethyl acetate or dioxan as solvent.

Abstract: A process for the manufacture of alpha , beta , gamma , delta -unsaturated esters containing a very high proportion of the 4(Z)-isomer, which are valuable perfume and flavor materials. The alpha , beta , gamma , delta -unsaturated esters are manufactured by a Wittig synthesis from phosphoranes and fumaraldehyde-acid esters under specific conditions.

Abstract: Cyclopentane derivs. of formula (I) (where Ru = isopropyl or isopropenyl gp., R2 = 1-3C alkyl gp and R3 = H or a satd. or olefinically unsatd. 4C acyl) are used esp. as perfume agents in cosmetics washign- and cleaning agents. (I) are prepd. by reacting (where X = halogen, esp. Cl or Br), with aldehydes HC(R2)(CH3)-CHO in the presence of aq. soln. of strong bases and catalytic amts. of quaternary ammonium cpds. to give cpds. (III) and reducing (III) to the corresponding alcohol, which is then opt. converted into the R3-OH ester. (I) have a fresh smell which increases in musk-like quality with increasing size of the alkyl gps. R2 and R3.

Abstract: Cyclopentene derivatives (I) I where R1 is isopropyl or isopropenyl, R2 is alkyl of 1 to 3 carbon atoms, X is -CHO, a dialkyl acetal or 1,2- or 1,3-alkylene acetal thereof where the acetal radical is of 2 to 6 carbon atoms, -CH2OH or -CH2OCOR3 where R3 is hydrogen or alkyl or alkenyl of up to 3 carbon atoms. The manufacture of I from the corresponding halomethyl cyclopentenes and aldehydes R2-CH(CH3)-CHO in the presence of a base and a quaternary ammonium salt, followed if desired by acetalization or conversion of the -CHO group to the -CH2OH or -CH2O-CO-R3 groups. The compounds are useful as fragrance materials.

Abstract: Novel aldehyde derivs. of formula (I) (where R1 is H or 1-4C satd. hydrocarbyl; and R2-5 are H, 1-4C hydrocarbyl, 5-8C cycloalkyl or phenyl; or R1 +R2 and/or R4 + R5 is/are 3-6C alkylene) e.g. 1-(3-oxobutyl-2-methyl-5-(1-methyl-3-oxopropyl)-1-cyclopentene, have characteristic pleasant odours and can be used in perfumery and cosmetics, as well as for improving the odour of industrial prods. (I) are also useful as inters. for pharmacologically active cpds. thus, reductive amination of the carbonyl function(s) gives amines with anti-inflammatory activity. Intramolecular condensn. between the two carbonyl functions gives new substd. hexahydroazulenes useful as perfumes and as inters for anti-inflammatory azulenes (e.g. guaiazulene).

Abstract: 6-methyl-octa-5,7-dien-2-one of formula (I) CH2=CH-C(CH3)=CH-CH2-CH2-CO-CH3 (I) has novel olfactory props. and is an inter. in terpenes synthesis. It has a fruity melon odour with definite green notes. (I) may be prepd. by reacting methyl norbornenyl ketone with a soln. of a vinyl Mg halide or by ethynylating it and partially hydrogenating to form methyl vinyl norbornenyl carbinol, converting the latter in known manner to the ketone and pyrolysing the latter at pref. 400-500 degrees C under reduced pressure.
