Abstract: Novel 13-oxo.-bicyclo 10,3,0 pentadecanes or pentadecanes 1(12) are of formula (I) (where R1 is CH3 or C2H5 and A and B are either both H or form a double bond). (I), esp. when R1=CH3, have a fine, adherent musk odour. The odour of (I) is extremely close to best available musk odourants currently available. They are also intermediate for other novel, odoriferous cpds. as well as providing a synthetic route for the prodn. of muscone.

Abstract: Racemic pantolactone is resolved by sepn. of the salts of pentanoic acid with (-) or (+)-3-aminomethylpinane followed by reformation of the lactone. D(-) Pantolactone is converted into D(+) pantothenic acid D(+) panthenol and D(+) panthetine.

Abstract: A mixture of Z- and E-2-[2-methylprop-1-en-1-yl]-4-methyltetrahydropyran isomers, of the formulae Z-I and E-I containing not less than 85% of Z-I and not more than 15% of E-I, is prepared by a process wherein 2-[2-methylprop-1-en-1-yl]-4-methylenetetrahydropyran of the formula II II is hydrogenated over a platinum dioxide or platinum/charcoal catalyst in the presence of a strongly acidic cation exchanger. The product is a useful fragrance material which also occurs naturally and is known as rose oxide.

Abstract: 2-(1-methyl-eth-1-en-1-yl)-,2-(1-methyl-prop-1-en-1-yl)-, 2-(eth-1-en-1-yl)- and 2-(prop-1-en-1-yl)-4-methyl-2,3-dihydro-6H-pyrans substituted in the 2-position of the side chain by hydroxymethyl, acyloxymethyl, alkoxycarbonylmethyl, halomethyl or formyl. The novel 4-methyl-2,3-dihydro-6H-pyrans are obtained by reaction of 3-methyl-but-3-en-1-ol with an appropriately substituted unsaturated aldehyde in the presence of an acid catalyst. The products possess very interesting organoleptic properties.

Abstract: Bis-epoxy-dialkoxy-alkanes are valuable intermediates for the preparation of the sought-after aromatic 2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one. The novel bis-epoxy-dialkoxy-alkanes are obtained by reacting the corresponding alpha , alpha '-dihalo-1,2-diketones with an alkali metal hydroxide or an alkali metal alkoxide and an alkanol at from -20 DEG to +100 DEG C. To prepare the 2,5-dialkyl-4-hydroxy-2,3-dihydro-furan-3-ones, which are valuable aromatics, the novel bis-epoxy-dialkoxy-alkanes are heated with strong mineral acids or strong organic acids at from 60 DEG to 120 DEG C.
