Abstract:
The present invention relates to bi- and tricyclic ketones of the general formula (I)
wherein
the dashed lines independently of each other represent a single or a double bond,
X represents a group of the formulae X 1 to X 3
wherein the asterisk denotes the point of attachment to the rest of the molecule,
R 1a and R 1b , independently of each other, are selected from hydrogen or methyl, or R 1a together with R 1b form a methylene or ethylene group,
R 2 , R 3a , R 3b , R 4 , R 5a and R 5b , independently of each other, are selected from hydrogen or methyl,
R 6 is selected from hydrogen, methyl or ethyl, and
R 7 is methyl or ethyl,
to a method of preparing said bi- and tricyclic ketones, to the use of a bi- or tricyclic ketone or of mixtures of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof as aroma chemicals; to the use of a bi- or tricyclic ketone for modifying the scent character of a fragranced composition; to an aroma chemical composition containing a bi- or tricyclic ketone or a mixture of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof; and to a method of preparing a fragranced composition or for modifying the scent character of a fragranced composition, comprising incorporating a bi- or tricyclic ketone or a mixture of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof into said composition.
wherein
the dashed lines independently of each other represent a single or a double bond,
X represents a group of the formulae X 1 to X 3
wherein the asterisk denotes the point of attachment to the rest of the molecule,
R 1a and R 1b , independently of each other, are selected from hydrogen or methyl, or R 1a together with R 1b form a methylene or ethylene group,
R 2 , R 3a , R 3b , R 4 , R 5a and R 5b , independently of each other, are selected from hydrogen or methyl,
R 6 is selected from hydrogen, methyl or ethyl, and
R 7 is methyl or ethyl,
to a method of preparing said bi- and tricyclic ketones, to the use of a bi- or tricyclic ketone or of mixtures of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof as aroma chemicals; to the use of a bi- or tricyclic ketone for modifying the scent character of a fragranced composition; to an aroma chemical composition containing a bi- or tricyclic ketone or a mixture of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof; and to a method of preparing a fragranced composition or for modifying the scent character of a fragranced composition, comprising incorporating a bi- or tricyclic ketone or a mixture of two or more bi- and tricyclic ketones or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof into said composition.
