摘要: The invention discloses a novel intermediate for preparing tapentadol and analogues thereof, wherein the structural formula is shown as formula I or II, and the groups are defined as the specification. The invention further discloses a method for preparing the novel intermediate and use of the intermediate for preparing tapentadol and analogues thereof. The invention can remarkably improve the product yield and quality of tapentadol, reduce the production cost, and simplify the production procedure. The preparation process is environment friendly, thus more suitable for the requirements of industrial production.
