摘要: The new product 3-oximino-4-oxo-2,5-dimethyl-tetrahydrofuran is manufactured by oximation of the new product 3-carboxy-4-oxo-2,5-dimethyl-tetrahydrofuran with aqueous nitrous acid, nitrite esters or nitrosyl chloride. Because of its fine caramel-like fragrance it may be used for the manufacture of scents and flavor materials. In addition it presents an advantageous method of synthesis of the sought-after flavor material 4-oxo-3-hydroxy-2,5-dimethyl-4,5-dihydrofuran (furaneol).

摘要: Cyclopentene derivatives (I) ##STR1## where R.sup.1 is isopropyl or isopropenyl, R.sup.2 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, --CH.sub.2 OH or --CH.sub.2 OCOR.sup.3 where R.sup.3 is hydrogen or alkyl or alkenyl of up to 3 carbon atoms. The manufacture of I from the corresponding halomethyl cyclopentenes and aldehydes R.sup.2 --CH(CH.sub.3)--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 --CH.sub.2 OH or --CH.sub.2 O--CO--R.sup.3 groups. The compounds are useful as fragrance materials.

摘要: New polycyclic Diels-Alder adducts which are formed on reaction of 8-vinyl-tricyclo-[5,2,1,0.sup.2,6 ]-dec-8-ene or 8-hydroxy-8-vinyl-tricyclo-[5,2,1,0.sup.2,6 ]-decane with alkenes or alkynes having one or two activating substituents, e.g., --COOH, --COOCH.sub.3, --COOC.sub.2 H.sub.5, --CHO, --COCH.sub.3, --COC.sub.2 H.sub.5 or --CN. They have green, fresh, fruity and in some cases woody odors with long-lasting tenacity and/or fixing properties. They can be used as constituents of perfumes and of compositions for perfuming body care products, detergents and other consumer products.
