Abstract:
A compound of formula I wherein R1, R2, R3 and R4 can be independently selected from H or Me, n=0, 1, the dotted lines are indicating single bonds, or in case n=0 an isolated double bond at position 3′, or in case n=1 an isolated double bond at position 3′ or 4′, and the wavy bond is indicating an unspecified configuration of the adjacent double bond. Said compounds, as well as precursors capable to generate said compounds, are useful as fragrance ingredients.
Abstract:
A compound represented by the formula 1 wherein R1 is H, or when R2 and R3 is H, then R1 is CHR5CHR6CHO, CR5═CR6CHO or C(CH3)CHO, wherein R5, R6 each independently may represent H or methyl; R2 is H, or when R1 and R3 is H, then R2 is CHR5CHR6CHO, CR5═CR6CHO or C(CH3)CHO, wherein R5, R6 each independently may represent H or methyl; R3 is H, or when R1 and R2 is H, then R3 is CHR5CHR6CHO, CR5═CR6CHO or C(CH3)CHO, wherein R5, R6 each independently may represent H or methyl; and R4 is methyl or a branched or linear, saturated or unsaturated, unsubstituted or substituted (optionally with cyclopropyl groups), C2-C7 alkyl or alkenyl residue, preferentially isobutyl, isoamyl. Said compounds are useful as perfume ingredients in personal care and household care products.
