Definitions

  • the present invention relates to 2,3,5,5-tetramethylhexanal derivatives and their use as fragrances.
  • fragrance industry has a constant need for new fragrances with interesting fragrance notes.
  • the range of naturally available fragrances can be supplemented, on the other hand it is possible to make the necessary adjustments to changing fashionable tastes. It also makes it possible to meet the ever-increasing need for odor improvers for everyday products such as cosmetics and cleaning agents.
  • the present invention initially relates to 2,3,5,5-tetramethylhexanal derivatives of the general structure (I)
  • the invention relates to the use of compounds of the general structure (I) specified above as fragrances.
  • the compounds (I) according to the invention namely
  • the compounds (I) can be prepared by known synthetic methods of organic chemistry.
  • the compounds (I) enhance the harmony and charisma as well as the naturalness and also the adhesion, the dosage being matched to the desired fragrance note, taking into account the other constituents of the composition.
  • the compounds of the formula (I) are particularly suitable for modifying and enhancing known compositions. In particular, their extraordinary olfactory strength should be emphasized, which generally contributes to the refinement of the composition.
  • the compounds of formula (I) can be combined with numerous known fragrance ingredients, for example other fragrances of natural, synthetic or partially synthetic origin, essential oils and plant extracts.
  • the range of natural fragrances can include both volatile, medium and low volatile components.
  • the range of synthetic fragrances can include representatives from practically all classes of substances.
  • Natural products such as tree moss absolute, basil oil, agricultural oils such as bergotte oil, mandarin oil, etc., mastic absolute, myrtle oil, palmarosa oil, patchouli oil, petitgrain oil, wormwood oil, myrrh oil, olibanum oil, cedarwood oil, sandalwood oil, East Indian oil, guaiac oil Cabreuva,

  • the signals of the CH 2 groups next to the two asymmetric carbon atoms were more strongly split with signal centers at 1.1 and 1.3 ppm (doublets from the doublet, the signal at 1.3 ppm is accompanied by a corresponding signal from the presumed secondary component ).
  • Odor Dry, aldehydic, minty, green in the smell and weakly ionic in the after smell (after 24 hours on the smell strip).
  • Apparatus 1 L four-necked flask with stirrer and dropping funnel.
  • the olefinic H gave a signal for the minor component at 6.6 ppm and a signal (doublet from doublet) at 7.35 ppm.
  • the OH proton appeared (unchanged) as a broad signal with a maximum at 7.8 ppm.
