Improved cyclamenaldehyde derivatives, and fragrances and flavorings
including the derivatives, are disclosed. In particular, the derivatives
maintain the fragrance characteristics of cyclamenaldehyde, while
enhancing the odorant intensity. In addition, when present in a fragrance
they heighten the effect of the remainder of the formulation. Further,
they heighten the perceived intensity of other olfactory stimuli, e.g.
food and ambient smells. Also disclosed are methods of making the
derivatives, and articles of manufacture including the derivatives. The
derivatives are prepared by replacing the phenyl moiety in
cyclamenaldehyde with a thiophene moiety, which can be unsubstituted, or
substituted with one or two lower alkyl, preferably isopropyl groups. The
aldehyde group in cyclamenaldehyde can also be replaced with an acetal,
methyl ether, nitrile or ester functionality. The acetal groups can
provide the compounds with a long lasting flavor or fragrance, where the
acetals slowly hydrolyze to provide the aldehyde group in
cyclamenaldehyde. Examples of suitable articles of manufacture include
perfumes, colognes, candles, air fresheners, and disinfectant
compositions.
