Use
4-penten-1-ol,2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)- is a colorless liquid with a very powerful and natural sandalwood
note.
The material can be prepared starting from ??-campholenealdehyde: Condensation
with formaldehyde and subsequent reduction lead to 2-(2,2,3-trimethyl-3-
cyclopenten-1-yl)-2-propenol, which is reacted with an alkyl ortho-propanoate to yield an alkyl 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-4-pentenoate.
Reduction of the latter gives the fragrance material. It can be used to impart
a powerful and tenacious natural sandalwood note to a wide range of perfume
types.
