    Abstract: A process for efficiently producing unsaturated alcohols from alpha , beta -unsaturated aldehydes. The process comprises selectively reducing the aldehyde group of an alpha , beta -unsaturated aldehyde with an aluminum alcoholate in the presence of a primary or s econdary alcohol bearing two to eight carbon atoms to give an unsaturated alcohol represented by general formula (III), and is characterized by carrying out the reaction in the presence of a proton acid wherein R represents an alkyl group bearing one to three carbon atoms.

    Abstract translation: 本发明的目的在于从α,β-不饱和醛有效提供不饱和醇。 本发明提供一种制备不饱和醇的方法,该方法通过使用醇铝来选择性地还原具有2-8个碳原子的伯或仲醇存在下的α,β-不饱和醛的醛基,以产生不饱和醇, 作为由式(III)表示的化合物。 (其中R表示具有1至3个碳原子的烷基>其中通过加入质子酸进行反应。
