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 cis-unsaturated alcohols by reacting a cis-1-alkenylaluminum 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.
这项发明涉及制备作为风味和香味化合物有用的不饱和醇。更具体地说,这项发明涉及通过将顺式-1-烯基铝二烷基化合物与环氧化合物反应,然后进行水解来制备主要为顺式不饱和醇。烯基基团具有一个或多个碳-碳双键连接,并且碳原子数为5到20个,可以选择性地用1到12个碳原子的烷基和芳香基取代。
