Abstract
NEW MATERIAL:A cyclopentane derivative of formula I (Q is =O or -H and -OH; R is H, methyl; when Q is =O, the formula II is double bond, and when Q is -H and -OH, the formula II is single bond).
EXAMPLE: 2-(2', 2', 3'-Trimethyl-cyclopent-3'-enylethylidene)-cyclopentan-1-one.
USE: Lasting perfumery or modifier having sandalwood note. Useful in various fields such as foods and drinks, cosmetics, pharmacenticals, etc.
PROCESS: Condensation of 2, 2, 3-trimethylcyclopent-3-enylacetaldehyde III with a cyclopentanone derivative IV gives a compound V, which is catalytically reduced to afford the objective compound 2-(2', 2', 3'-trimethylcyclopent-3'-enylethyl)-cyclopentan-1-one derivative VI.
