Abstract: 4-isopropylcyclohexylmethanol and its alkyl ethers of the general formula I (I) where R1 is H or C1-C4-alkyl, are prepared by a process in which the novel 4-(1-alkoxy-1-methylethyl)-benzaldehyde or its dialkyl acetal of the general formula II (II) where X is oxygen (IIa) or its two R2O groups (IIb) and R2 and R3 are each C1-C4-alkyl, is heated to 100 DEG -250 DEG C., preferably 130 DEG -200 DEG C., under a hydrogen pressure of from 50 to 350, preferably from 150 to 300, bar in the presence of a noble metal of group VIII of the Periodic Table.

Abstract: 1. A process for the preparation of a 1-alkoxyisochroman of the general formula see diagramm : EP0179377,P5,F3 where R is alkyl of 1 to 4 carbon atoms, and the radicals R**1 and R**2 are identical or different and each is hydrogen, or linear or branched alkyl of 1 to 9 carbon atoms, wherein an isochroman of the general formula see diagramm : EP0179377,P5,F4 where R**1 and R**2 have the above meanings, is oxidized electrochemically in the presence of an alkanol of the formula ROH, where R has the above meaning.

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.
