摘要:
Tricyclic carboxylic acid esters having the formula: ##STR1## wherein R is an alkyl group of 2 or 3 carbon atoms. These compounds have a woody fragrance and are useful as components of perfume compositions.
摘要:
Fragrant cyclohexanol derivatives are produced by condensing 2-ethylidene-5-norbornene with a phenol compound, in the presence of a Friedel-Crafts catalyst; and hydrogenating the condensation product in the presence of a metal catalyst.The compounds so produced have a green-floral odor and are advantageously used in soaps, detergents, shampoos, hair rinse, cosmetics, colognes and perfumes.
