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.
