Ethyl (S) -1-phenyl-1,2,3, 4-tetrahydro-2-isoquinolinecarboxylate is an important organic compound, and the common synthesis methods are as follows.
One is to use phenethylamine and ethyl acrylate as starting materials and undergo the Pictet-Spengler reaction. This reaction needs to be carried out in the presence of acidic catalysts such as p-toluenesulfonic acid.

In this method, the activity and selectivity of palladium catalyst have a significant impact on the reaction results. At the same time, factors such as ligands, types and dosages of bases in the reaction system also need to be carefully regulated.
The third is to start from a simple benzene ring and a nitrogen-containing heterocyclic compound, and construct the target molecule through multi-step reactions. For example, a specific substitution reaction of the benzene ring is first carried out to introduce a suitable functional group, and then it is gradually synthesized with nitrogen-containing heterocyclic fragments through condensation, cyclization and other Although there are many steps in this path, the reaction conditions of each step can be flexibly adjusted to achieve precise control of the stereochemistry and functional groups of the product.
