Provided is a method for the production of 1-menthol, which comprises hydrogenation of piperitenone with a transition metal complex of a specified optically active phosphine to produce pulegone, hydrogenation of the obtained pulegone with a ruthenium-phosphine-amine complex in the presence of base to obtain pulegol, and further hydrogenation of the pulegol with a transition metal catalyst.
提供了一种生产1-薄荷醇的方法,包括将
环戊酮薄荷脑与特定光学活性膦
金属配合物进行加氢反应以产生薄荷醛,然后将获得的薄荷醛与
钌-膦-胺配合物在碱存在下进行加氢反应以获得薄荷醇,最后再通过过渡
金属催化剂对薄荷醇进行进一步加氢。
