    General Preparation Method for a Compound of the Formula (I)

    Preparation example: 1-cyclopent-2-en-1-ylpropan-2-one

    [0323] ##STR00034##

    [0324] A 100 ml three-neck flask with magnetic stirrer, contact thermometer, dropping funnel, 5 cm Vigreux column and distillation apparatus is initially charged with 69 mg (0.34 mmol) of aluminum triisopropoxide and 4.6 g (0.035 mol) of ethyl acetoacetate and heated up to 180 C. At this temperature, a solution of 12.6 g (0.15 mol) of 2-cyclopentanol and 21 g (0.16 mol) of ethyl acetoacetate is added dropwise within 2 h, with constant removal of distillate and evolution of carbon dioxide. The mixture is stirred at 180 C. for another 2 h. The residue (13 g) is distilled using a Kugelrohr (boiling range: 110 C./80-40 mbar). 8.1 g of distillate are obtained (GC: 84% product). 2.7 g of the distillate are subjected to preparative column treatment on 120 g of silica gel 60 with hexane/ethyl acetate (Bchi PrepChrom C-700, column: 120 g (SepaCore)). Yield: 1.5 g (GC: 99% product).

    [0403] The compounds of the formula (I) or (Ia) push the fresh and minty notes. A transparent, watery effect is the result and makes the composition seem cleaner. The effect is assessed as being particularly marked with the compounds XIV and XXIII.

    [0404] Here, the compounds of the formula (I) or (Ia) turn the fragrance in a herby direction. A sweet impression is the result, the lavender/coumarin note of which seems much more marked. At the same time, the camphor-like note is covered a little. The effect is assessed as being particularly marked with the compounds XV and XXII.

    [0405] The compounds of the formula (I) or (Ia) push the freshness here too. The slightly metallic minty note is distinctly reduced and rounded off. The effect is assessed as being particularly clear with the compounds XX and XXI.
