The present invention relates to novel 1,3-dioxane derivatives of formula (I)
wherein each of R1 and R2 is a hydrogen atom, R3 and R4 are independently a hydrogen atom, a linear or branched C1-C6 alkyl group, or a linear or branched C2-C6 alkenyl group, and R5 is a linear or branched C1-C6 alkyl group, a linear or branched C2-C6 alkenyl group or a (CH2)0-2 - aryl group, and R6 and R7 are independently a hydrogen atom, a linear or branched C1-C6 alkyl group, a linear or branched C2-C6 alkenyl group or a (CH2)0-2 - aryl group, or R6 and R7 together with the carbon atom to which they are attached form a C5-C6 cycloalkyl group or a C5-C6 cycloalkenyl group, substituted or not; their preparation and their use as organoleptic compounds.

The invention is directed to the use of compounds of formula (I), as fragrant agents. In this formula: - R3 and R4 are independently a hydrogen atom, a C1-C6 alkyl group or a C2-C6 alkenyl group, R5 is a C1-C6 alkyl group, a C2-C6 alkenyl group or a (CH2)0-2-aryl group, R6 is a C1 -C6 alkyl group, a C2-C6 alkenyl group, a (CH2)0-2-aryl group or a C5- C6 cycloalkyl or cycloalkenyl group, and R7 is a hydrogen atom, a C1-C6 alkyl group or a C2-C6 alkenyl group; or R3, R4 and R5 are as above defined, and R6 and R7 together with the carbon atom to which they are attached form a C5-C6 cycloalkyl or cycloalkenyl group.
Disclosed is a method of repelling noxious insects comprising the step of exposing said noxious insects to a composition containing from 0.1 to 90 wt. %, based on the total weight of the composition, of at least one of 2-(1-hydroxyalkyl)cycloalkanones represented by the following formula 11:
1
wherein n is an integer of 3-10, R
1
is hydrogen or a straight-chain saturated hydrocarbon radical having 1-6 carbon atoms; R
2
is hydrogen or methyl group and R
m
′ represents m′ of the same or different, straight-chain or branched, saturated or unsaturated, hydrocarbon radicals R which, as a substituent group, can be bonded to carbocyclic atoms; m′ is an integer of 0-8, provided that m′ should be at least 2 when n is at least 4 and both the R
1
and R
2
are alkyl groups; the sum of the carbon atoms of R
m
′ does not exceed 12; and, further, when n is 4, R may be an isopropylidene group which intramolecularly bridges between the third and sixth carbocyclic atoms.
