Abstract
Acetal derivatives of 2,2,3,6-tetramethyl-1-cyclohexane/ene-carbaldehyde of formula (I): for use in the perfumery industry as well as the resulting compositions or articles containing one or more of these compounds. In formula (I), one dotted line indicates the presence of a carbon-carbon single or double bond and the other dotted line indicates the presence of a carbon-carbon single bond, R1 represents a hydrogen atom or a methyl or ethyl group; and each R, taken alone, simultaneously or independently, represents a C1-3 alkyl or alkenyl group, or the R groups, taken together, represent a C2-6 hydrocarbon group optionally including an oxygen atom.
