Abstract: p-Alkoxycyclohexylalkanols and their esters of the general formula I where R1 is C1-C7-alkyl, in particular tert.-butyl, or is cyclohexyl, R2 is C1-C3-alkyl, in particular methyl or ethyl, and R3 is hydrogen, acetyl, propionyl or butyryl, and scent compositions containing these compounds I and processes for their preparation. The novel compounds have fine woody or sandalwood notes and can be used as scents and as components of scent compositions.
