There are several common synthesis methods of (3R) - 2 - (tert-butoxycarbonyl) - 1, 2, 3, 4 - tetrahydroisoquinoline - 3 - carboxylic acid.
First, the tetrahydroisoquinoline skeleton is constructed by multi-step reaction with suitable starting materials, and the required functional groups are introduced. First, phenethylamine compounds with specific substituents are selected to undergo Pictet-Spengler reaction with aldehyde substances under suitable conditions. This reaction can efficiently construct tetrahydroisoquinoline ring system. After that, the amino group is protected by tert-butoxycarbonyl using a suitable protecting group strategy, and then the carboxyl group is appropriately modified and introduced, and the target product can be obtained through multi-step transformation.
Second, it can be obtained from compounds with similar structures and converted by functional groups. For example, compounds containing tetrahydroisoquinoline structure and carboxyl groups or their precursors already exist are prepared first, and then other positions are modified. The tetrahydroisoquinoline derivative with specific substitution is introduced into tert-butoxycarbonyl through selective reaction, and the carboxyl group is precisely converted and adjusted to achieve the synthesis of the target product.
Third, the reaction strategy of transition metal catalysis is adopted. Using the unique activity and selectivity of transition metal catalysts, the formation of carbon-carbon bonds or carbon-heterobonds can be achieved. By designing a specific substrate to cyclize under the catalysis of transition metals, the tetrahydroisoquinoline structure is constructed, and then tert-butoxycarbonyl and carboxyl are ingeniously introduced to achieve the synthesis of the target compound.
These common synthesis methods have their own advantages and disadvantages. In actual synthesis, it is necessary to comprehensively consider many factors such as the availability of raw materials, the requirements of reaction conditions, and the purity requirements of the target product, and choose the most suitable one.
