reduction of primary amides into the corresponding amines using a polymethylhydrosiloxane (PMHS)–Ti(OiPr)4 reducing system is described. Aromatic as well as aliphatic primary amides are reduced in high selectivity and excellent yields. The reduction could proceed via dehydration of the primary amide group into the corresponding nitrile which is then reduced into the corresponding primary amine.
描述了一种使用聚甲基氢硅氧烷(PMHS)–Ti(O i Pr)4还原体系将伯酰胺还原为相应胺的简单而有用的方法。芳族伯酰胺和脂族伯酰胺的高选择性和优异的收率得到降低。还原可通过将伯酰胺基脱水成相应的腈而进行,然后将其还原成相应的伯胺。
