摘要:
This invention relates to unsaturated alicyclic carbonyl compounds of formula (I) wherein R is C1 to C4 alkyl; or R is vinyl or a linear, branched or cyclic C3 to C4 alkenyl; X is carbonyl or a divalent radical —(CMe2)-; and Y is oxygen or a divalent radical —(CH2)—.
摘要:
The present disclosure refers to sila-substituted carbinols of formula (I) wherein R1, R2 and R3 are independently selected from C1-C4 alkyl or C3-C4 cycloalkyl; R4 is methyl or ethyl; and R5 is methyl or ethyl. The disclosure further refers to their preparation and to perfume compositions and fragrance applications comprising them.

摘要:
The invention relates to 1,2-substituted 2,3-dihydro-1H-5,9-dioxacyclohepta[f]inden-7-ones and 7-substituted benzo[b][1,4]dioxepin-3-ones and to the use of these compounds in fragrance compositions.
摘要:
Provided is class of compounds of formula (I) wherein X, R1, R2 and R3 have the same meaning as given in the specification capable of releasing fragrant compounds in a controlled manner into the surroundings.
摘要:
A compound of the formula I n which R1 is H or methyl, R2 is H, methyl or ethyl, R3 and R4 are independently hydrogen, methyl, ethyl, n-propyl or iso-propyl, and the dashed lines representing the alternative possibilities of there being present either an additional double bond or an additional group R5, which is H or methyl.The compounds possess a marine odour with sweet character, and are useful in fine and functional fragrances.
