scalable route to racemic and highly enantiomerically enriched menthylamines exploits the technical product rac-neomenthol as the starting material. The elaborated protocol is based on nucleophilic substitution of the hydroxy moiety by azide. Subsequent reduction and resolution with tartaric acid provides the desired optically enriched menthylamines. amines - azides - chiral resolution - reduction - terpenoids
可靠的,可扩展的途径生产外消旋和高度对映异构体富集的薄荷胺,采用了技术产品外消旋-薄荷脑作为原料。精心设计的方案基于叠氮化物对羟基部分的亲核取代。随后用酒石酸还原和拆分得到所需的光学富集的薄荷胺。 胺-叠氮化物-手性拆分-还原-萜类化合物
