Synthesis of Compounds of Formula (I)

a) Preparation of a Mixtures of 3-[5-(2-propanyl)-1-cyclohexen-1-yl]propanal and its Isomer 3-[3-(2-propanyl)-1-cyclohexen-1-yl]propanal

i) 7-isopropyl-1-oxaspiro[4.5]decan-2-one

[0070]3-isopropyl-1-cyclohexanol (140 g; 984 mmol; 2 eq.) was heated in an oil bath at 155° C. under nitrogen. Di-tert-butyl peroxide (18.36 g; 123 mmol; 0.25 eq.) and n-butyl acrylate (63.7 g; 492 mmol; 1 eq.) were added simultaneously and separately over a period of 1 hour. After 4 more hours at 150° C., the reaction was cooled to 50° C. and MTBE (100 mL) was added, followed by 30% aqueous NaOH solution (118 g; 886 mmol). After stirring for 30 minutes, water (140 mL) was added, followed by MTBE (140 mL). The phases were separated and the aq. phase was treated with diethyl ether (2×300 mL) and MTBE (300 mL). Each organic phase was treated with water (210 mL). The combined aqueous phases were treated with 50% aqueous H2SO4 solution (280 g), extracted twice with diethyl eth...

Abstract

The present invention concerns compound of formula
in the form of any one of its stereoisomers or a mixture thereof, and wherein the exocyclic dotted line represents a carbon-carbon single or double bond, and one endocyclic dotted to line represents a carbon-carbon single bond and the other endocyclic dotted line represents a carbon-carbon double bond; and R, R1 and R2 represent, independently from each other, a hydrogen atom or a C1-3 alkyl group; and their use in perfumery to impart odor notes of the green, floral type.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of perfumery. More particularly, it concerns the use as perfuming ingredient of compounds of formula (I) as defined below, which are useful perfuming ingredients of the green, floral type. Therefore, following what is mentioned herein, the present invention comprises the invention's compound as part of a perfuming composition or of a perfuming consumer product.PRIOR ART[0002]To the best of our knowledge, the compounds of formula (I) are novel.[0003]To the best of our knowledge, the prior art reports some structural analogues as perfuming ingredients.[0004]WO 08 / 053148 reports some cyclohexyl (i.e. saturated) analogues of the present invention which are described as having perfuming properties of the lily of the valley type. Said document does not suggest unsaturated compounds, and the only compounds having also green note do have a significantly different substitution pattern compared to the present ones.[0005]US 2009 / 0...
