Abstract:
Disclosed are compounds having the ability to modulate, namely to improve, enhance and or modify fragrance compositions due to their ability to inhibit cytochrome P450 enzymes, e.g. CYP2A13 and CYP2B6.
Abstract:
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products. Such perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume communities options as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles.
Abstract:
Aromatic carbonyl compounds of general formula (I), wherein the radicals R to R are, independently of one another, hydrogen or an alkyl group with 1 to 4 C atoms, the radical R is hydrogen or an alkyl group with 1 to 4 C atoms and Ph is a phenyl group, are characterized by interesting fragrance qualities of great radiance and can be used as scents, for example in cosmetics, technical products or alcohol-based perfumes.

Abstract:
The present invention relates to a method for the synthesis of alpha , beta -unsaturated ketones which comprises, in the method for the synthesis of alpha , beta -unsaturated ketones represented by general formula (I) (where R is an aliphatic group with a side chain at the 1 position, an alicyclic group, a substituted alicyclic group, a heterocyclic group, a substituted heterocyclic group, a phenyl group or a substituted phenyl group), reacting aldehydes represented by general formula (II): R CHO (where R is as defined above) with alkali metal salt of acetoacetic acid represented by general formula (III) (where M is an alkali metal ion), in the presence as a catalyst of 3-azabicyclo[3,2,2] nonane, a cyclic secondary amine represented by general formula (1) (where n is 3 or more and up to 5, m is 1 or more and up to 10, R is an alkyl group having 1 to 10 carbon atoms and of straight chain or with side chains, an alkyl group substituted by alicyclic groups or phenyl groups, an alicyclic group which may be substituted by lower alkyl groups, or a phenyl group which may be substituted by lower alkyl groups, and an R substitution position is at a carbon atom other than the two adjacent to N), a cyclic secondary amine represented by general formula (2) (where l is 1 or more and up to 6, a ring with N is a 6-membered, 7-membered or 8-membered ring, the two neighbors of N are methylene, R is a lower alkyl group, its substitution position is at a carbon atom other than the two adjacent to N, and (a) is an alicyclic group or a phenyl group), or a secondary amine represented by general formula (3): CH3NHCH2R (where R is an aliphatic group having 5 to 17 carbon atoms and of straight chain or with side chains, an alicyclic group which may be substituted by lower alkyl groups, a phenyl group which may be substituted by lower alkyl groups, or an alkyl group substituted by phenyl groups), in a mixture solvent of water and water-insoluble organic solvent, while keeping the pH constant with mineral acid, and by adjusting the amount of water.
