What are the synthesis methods of (S) -6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid hydrochloride?

The method of preparing (2S) -6,7-diethoxy-1,2,3,4-tetrahydroisoquinoline-3-formamide has its own way.

First, the corresponding isoquinoline derivative can be started. First, the ethoxy group is introduced into the isoquinoline ring with appropriate reagents and conditions. This step requires careful selection of the reaction solvent and catalyst to maintain the precise access of the ethoxy group at positions 6,7. After the ethoxy group is successfully introduced, other check points on the ring are modified to achieve the state of tetrahydro. Or by catalytic hydrogenation, in the presence of a suitable catalyst such as palladium carbon, at a suitable temperature and pressure, the isoquinoline ring is partially hydrogenated to obtain a tetrahydroisoquinoline structure. Then, for the 3 position, the formamide group is added through an acylation reaction. This acylation reaction, or a suitable acylation reagent, such as formyl chloride or formate esters, is mildly reacted in the presence of a base, and the final product is obtained.

Second, the construction of an isoquinoline ring can also be started. With suitable nitrogen-containing and carbon-containing raw materials, through a series of reactions such as condensation and cyclization, the isoquinoline mother nucleus is constructed. In the cyclization process, the introduction of ethoxy groups is planned synchronously, so that when the cyclization is formed, the 6,7 positions are ethoxy. After the cyclization, the tetrahydro structure is obtained by hydrogenation with the above method, and then the 3-position acylation is carried out to obtain (2S) -6,7-diethoxy-1,2,3,4-tetrahydroisoquinoline-3-formamide.

Preparation methods have their own advantages and disadvantages. Only by carefully choosing according to many factors such as the availability of raw materials, the difficulty of reaction, and cost considerations can the synthesis of the target product be achieved efficiently and economically.
