PREPARATION OF UNSATURATED ALCOHOLS

摘要

This invention relates to the preparation of unsaturated alcohols useful as flavor and fragrance compounds. More specifically, this invention relates to the preparation of predominately cisunsaturated alcohols by reacting a cis-l-alkenyl-aluminum dialkyl compound with an epoxide compound followed by hydrolysis. The alkenyl moiety has one or more double bond carbon-to-carbon linkage and from 5 to 20 carbon atoms that can be optionally substituted with the substituents selected from alkyl and aromatic radicals having 1 to 12 carbon atoms.
