摘要: The present application relates to the field of drug synthesis, in particular to a novel intermediate, a method for preparing the same and application thereof. The structural formula of the novel intermediate provided by the present application is as expressed by formula I:
where R is a secondary amine protection group. Based on the possible biogenic pathway of morphine derivatives, the present application realizes the efficient synthesis of morphine derivatives through the strategy of biomimetic synthesis, taking the asymmetric transfer hydrogenation reaction and the intramolecular oxidative dearomatization Heck reaction in the process of preparing the intermediate as the key reactions of total synthesis. Using the novel intermediate provided by the present application to synthesize morphine derivatives has the characteristics of significantly reducing the synthesis steps, improving the yield, reducing the discharge of three wastes and reducing the production cost.-
