There are various ways to synthesize Boc - D - Tetrahydroisoquinoline - 3 - COOH. The most common one is to use D-tetrahydroisoquinoline as the starting material, and first use a suitable protective group, such as tert-butoxycarbonyl (Boc), to protect its amino group. This protection method is mostly Boc-acid anhydride ((Boc) 2O) and organic bases, such as triethylamine (Et 🥰 N), synergistically act on D-tetrahydroisoquinoline, and react in a suitable solvent, such as dichloromethane (CH ² Cl ²), at low temperature or room temperature. After a while, the amino group is protected by the Boc group.
Then, the product of the protected amino group is carboxylated. Carboxyl dioxide is often used as the carboxyl source. Under the action of metal reagents such as n-butyl lithium (n-BuLi) or Grignard reagent (RMgX), the substrate is reacted with carbon dioxide in a low temperature, anhydrous and oxygen-free environment, and carboxyl groups can be introduced. After the reaction is completed, the pure Boc-D-tetrahydroisoquinoline-3-carboxylic acid can be obtained through appropriate separation and purification methods, such as column chromatography and recrystallization.
Another synthesis method is to use benzene ring derivatives containing suitable substituents as the starting material, and construct the tetrahydroisoquinoline skeleton through multi-step reaction, and then introduce the Boc protecting group and the carboxyl group in turn. First, the tetrahydroisoquinoline structure is constructed by the reaction of benzene ring derivatives and appropriate amine compounds through condensation, cyclization, etc. Subsequent to the above similar method, the amino group is first protected, and then the carboxyl group is introduced, which can also achieve the purpose of synthesis.
The key to the synthesis lies in the precise control of the reaction conditions. The yield and selectivity of each step of the reaction need to be fine-tuned. The purity of the reagents and solvents used also has a great influence on the reaction, and the separation and purification steps are also related to the purity and quality of the final product.

It is difficult to determine the price of Boc-D-tetrahydroisoquinoline-3-carboxylic acid. The change in its price is subject to various factors.
First, it comes from raw materials. If the raw materials for this product are easy to obtain and inexpensive, the price may be slightly reduced; if the raw materials are rare and difficult to purchase, the price must be high.
Second, it is related to the production method. If the production method is simple and efficient, the cost of labor and materials is small, and the price may be low; if the production method is complicated, time-consuming and labor-intensive, and the cost increases greatly, the price will rise.
Third, it depends on demand. There are many people who need it in the market, and the demand exceeds the supply, and the price will rise; if the demand is small, the supply exceeds the demand, and the price will tend to drop.
Fourth, it involves the manufacturer. Different manufacturers have different pricing due to their coarse technology and reputation. The products of famous factories are of high quality and trust, and the price may be high; the products of small factories may be inferior due to quality and trust, and the price may be different.
Looking at the market conditions, the price per gram may range from a hundred yuan to several thousand yuan. If you want to get a definite price, you should ask a merchant specializing in chemical reagents, or you can get a fair price in the near future.
