Definitions
- the invention relates to substituted 2-carbonylbenzofurans and substituted 2-carbonyl-2,3-dihydrobenzofurans in fragrance compositions.
- the compounds (I) are either known or can be prepared analogously to known processes.
- the 2-carbonylbenzofurans (IV) can be prepared according to the following scheme:
- crown ethers as phase transfer catalysts gives similar 2-carbonylbenzofurans in yields of about 53% (RB Gammill and SA Nash, J. Org. Chem. 51 (1985), 3116).
- Another method for preparing the 2-carbonylbenzofurans (IV) is the gentle acylation of 2- (trimethylsilyl) benzofuran compounds starting from the corresponding benzofuran derivatives according to M. Gill in Tetrahedron 40 (1984), 621.
- the 2-carbonyl-2,3-dihydrobenzofurans of the formula can be prepared by reduction from the above-mentioned 2-carbonylbenzofurans (IV), for example by hydrogenation in ethanol using hydrogen in the presence of a Pd catalyst and subsequent oxidation with pyridinium chlorochromate in dichloromethane.
- the compounds (I) to be used according to the invention have interesting ones Fragrance properties:
- 2-acetylbenzofuran in addition to the usual, is almond and flowery Smell also has a fine anthranil-like and coumarin note, which in Compositions through their fullness and softness an excellent harmonization causes.
- the 2-carbonyl-2,3-dihydrobenzofurans are generally related to their olfactory Properties similar to the 2-carbonylbenzofurans used. Yet the 2-carbonyl-2,3-dihydrobenzofurans have further grades: for example with 2-acetyl-2,3-dihydrobenzofuran also a green, melon-like and light floral smell present.
- the 2-acetyl-2,3-dihydro-3-methylbenzofuran has a lily of the valley smell and has a high diffusion, which has a great impact in compositions generated.
- the compounds (I) are notable for high stability towards the various acidic, neutral and acalic media.
- a Solution of the compounds (I) in toluene in hydrochloric acid or in sodium hydroxide solution higher temperatures are stirred largely undamaged.
- the compounds (I) to be used according to the invention are readily compatible with other fragrances in different, different proportions combine novel, interesting fragrance compositions, the amount 0.01 to 10 wt .-%, based on the whole Composition.
- compositions can be used for perfuming of cosmetics such as creams, lotions, aerosols, toilet soaps, household products, such as cleaning agents and detergents, fabric softeners, disinfectants and textile treatment agents, the amount of fragrance compositions 0.1 to 40 wt .-%, preferably 0.5 to 20 wt .-%, based on the whole product.
- compositions, application examples 1 to 4 are suitable preferably for fine perfuming of cosmetics such as creams, lotions, aerosols and toilet soaps.
