Abstract
An aryl-substituted alkanal compound having a molecular weight of less than 300 g/mol and which bears a substituent on the aryl ring ortho to a substituent bearing the aldehyde functionality. Said compounds are useful as perfume ingredients in personal care and household care products.
Claims16
An aryl-substituted alkanal compound having a molecular weight of less than 300 g/mol and which bears a substituent on the aryl ring ortho to a substituent bearing the aldehyde functionality, and is represented by Formula 1
- wherein,
- R1, R2, R3, R6 and R7 each independently may represent H or methyl;
- R4 is H, or when R5 is H, R4 is a C1-C7 branched or linear, saturated or unsaturated, unsubstituted or substituted, optionally with cyclopropyl groups, alkyl radical;
- R5 is H, or when R4 is H, R5 is a C1-C7 branched or linear, saturated or unsaturated, unsubstituted or substituted, optionally with cyclopropyl groups, alkyl radical;
- or
- R4 and R5 together with the carbon atoms to which they are attached, form a substituted or unsubstitued 5-membered ring;
- n=0, 1, 2;
- the dotted line represents an optional single bond, with the proviso that when the dotted line represents a single bond R4 or R5 are sec-butyl, iso-butyl or a C5-C7 branched or linear, saturated or unsaturated alkyl residue;
- and
- wherein the compounds are not selected from 5-(tert-butyl)-2-methyl-2,3-dihydro-1H-indene-2-carbaldehyde, 5-(tert-butyl)-2,3-dihydro-1H-indene-2-carbaldehyde, 5-isopropyl-2,3-dihydro-1H-indene-2-carbaldehyde, 5-isopropyl-2-methyl-2,3-dihydro-1H-indene-2-carbaldehyde, 5-ethyl-2,3-dihydro-1H-indene-2-carbaldehyde, 5-ethyl-2-methyl-2,3-dihydro-1H-indene-2-carbaldehyde, 5-methyl-2,3-dihydro-1H-indene-2-carbaldehyde, 2,5-dimethyl-2,3-dihydro-1 H-indene-2-carbaldehyde, 3-(5-(tert-butyl)-2-methylphenyl)propanal, 3-(5-(tert-butyl)-2-methylphenyl)-2-methyl propanal, 3-(5-isopropyl-2-methylphenyl)propanal, 3-(5-isopropyl-2-methylphenyl)-2-methylpropanal, 3-(5-ethyl-2-methylphenyl)propanal, 3-(5-ethyl-2-methylphenyl)-2-methylpropanal, 3-(4-(tert-butyl)-2-methylphenyl)propanal, 3-(4-(tert-butyl)-2-methylphenyl)-2-methylpropanal, 3-(4-isopropyl-2-methylphenyl)propanal, 3-(4-isopropyl-2-methylphenyl)-2-methylpropanal, 3-(4-ethyl-2-methylphenyl)propanal, 3-(4-ethyl-2-methylphenyl)-2-methylpropanal or a compound of formula 3
- wherein R1 through R5 is independently H or methyl.
An aryl-substituted alkanal compound having a molecular weight of less than 300 g/mol and which bears a substituent on the aryl ring ortho to a substituent bearing the aldehyde functionality, represented by Formula 2
- wherein R1, R2, R3, and R6 each independently may represent H or methyl;
- R4 is H, or when R5 is H, R4 is a C1-C7 branched or linear, saturated or unsaturated, unsubstituted or substituted, optionally with cyclopropyl groups, alkyl radical;
- R5 is H, or when R4 is H, R5 is a C1-C7 branched or linear, saturated or unsaturated, unsubstituted or substituted, optionally with cyclopropyl groups, alkyl radical;
- or R4 and R5 together with the carbon atoms to which they are attached, form a substituted or unsubstitued 5-membered ring;
- and wherein the compounds are not 3-(5-(tert-butyl)-2-methylphenyl)propanal, 3-(5-(tert-butyl)-2-methylphenyl)-2-methylpropanal, 3-(5-isopropyl-2-methylphenyl)propanal, 3-(5-isopropyl-2-methylphenyl)-2-methylpropanal, 3-(5-ethyl-2-methylphenyl)propanal, 3-(5-ethyl-2-methylphenyl)-2-methylpropanal, 3-(4-(tert-butyl)-2-methylphenyl)propanal, 3-(4-(tert-butyl)-2-methylphenyl)-2-methylpropanal, 3-(4-isopropyl-2-methylphenyl)propanal, 3-(4-isopropyl-2-methylphenyl)-2-methylpropanal, 3-(4-ethyl.-2-methylphenyl)propanal, 3-(4-ethyl-2-methylphenyl)-2-methylpropanal, or a compound of formula 3
- wherein R1 through R5 is independently H or methyl.
