摘要:
The compound 4-exo-hydroxy-endo-tricyclo[5.2.2.0.sup.2,6 ]-undec-8-ene having the formula (I): ##STR1## is prepared by subjecting endo-tricyclo[5.2.2.0.sup.2,6 ]undeca-3,8-diene having the formula (II): ##STR2## to oxymercuration and reduction with sodium borohydride.
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.
