Tert-Butyl 6-Amino-3,4-Dihydroisoquinoline-2(1H)-Carboxylate

Tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylic acid ester has a wide range of uses. In the field of medicinal chemistry, it is often used as a key intermediate to assist in the synthesis of many drugs. For example, when developing isoquinoline compounds with specific physiological activities, it can cleverly build the basic structure of drug molecules through various reactions, such as nucleophilic substitution and acylation with specific reagents, and lay the foundation for the creation of new drugs.
In the field of organic synthesis chemistry, it also plays an important role. Because of its special activity check point, it can participate in the construction of complex organic molecules. Chemists can precisely modify their amino and carboxyl esters and other functional groups to achieve subtle regulation of reaction pathways and product structures, and synthesize a series of organic compounds with novel structures and unique functions to meet the needs of different fields such as material science and total synthesis of natural products.
In addition, in the early stage of drug development activity screening and lead compound optimization, tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylic acid esters are used as starting materials. After structural modification and modification, many derivatives derived can be used to evaluate the relationship between structure and activity, providing rich materials and research directions for the search for high-efficiency and low-toxicity lead compounds.

The synthesis method of tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylate is not directly recorded in the classic "Tiangong Kaiwu", but according to the principles of ancient and modern chemistry, relevant synthesis ideas can be found.
To obtain this substance, first, you can first find a suitable starting material, such as a compound with isoquinoline structure as the base. First, it is modified with a protecting group to protect the specific position and avoid side branches during the reaction. The tert-butyl protecting group is selected to react with the corresponding active compound and introduce the tert-butyl protecting group. This process requires fine temperature control and timing adjustment to ensure that the reaction proceeds in the expected direction.
Second, the introduction of amino groups is also critical. Nucleophilic substitution or reductive amination can be used. If nucleophilic substitution is used, a suitable halogenate or sulfonate should be selected, and the reaction with the reagent containing amino groups should be catalyzed by an appropriate solvent and base. During the reaction, the polarity of the solvent and the strength of the base all affect the reaction effect. If reductive amination is selected, the aldehyde or ketone condenses with ammonia or amine first, and then the imine is reduced to amine with a reducing agent. The choice of reducing agent is crucial, and the reaction activity and selectivity must be balanced.
Third, when the structure of dihydroisoquinoline is constructed, the cyclization reaction can be used. Such as compounds containing aryl groups and alkenyl groups, under the catalysis of metal catalysts or acids, are cyclized within molecules to form isoquinoline parent nuclei. The amount of catalyst, reaction temperature and time all need to be precisely grasped to obtain the ideal yield and purity.
The whole process of synthesis has strict requirements on reaction conditions, reagent purity and operation skills. Although "Tiangong Kaiji" does not describe the synthesis of such compounds in detail, the spirit of "exhaustive investigation and experiment" is the basis of today's synthetic chemistry. By means of ancient methods and modern techniques, the synthesis of tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -formate can be explored.

Tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylic acid ester is one of the organic compounds. Its physical properties are worth exploring.
Looking at its properties, it may be a white to off-white solid under normal conditions. This is a common state of many similar organic compounds. Due to the arrangement and interaction of molecular structures, it presents this stable aggregation state.
The melting point is about a specific temperature range, which is crucial for the identification and purification of the compound. The melting point can be accurately determined by a melting point meter, and its specific value depends on the strength of intermolecular forces, such as hydrogen bonds, van der Waals forces, etc. In terms of solubility, in organic solvents, such as common ethanol, dichloromethane, etc., it exhibits a certain solubility. Ethanol, with moderate polarity, can form intermolecular forces with some groups of the compound, such as hydrogen bonds, etc., so that it is soluble; although dichloromethane has weak polarity, its molecular structure can also interact with the compound and allow it to dissolve. However, in water, its solubility is relatively small. Due to the large difference between the polarity of the compound as a whole and the polarity of water, the hydrogen bond network formed by water is difficult to accept this compound molecule.
Density is also one of its important physical properties. Its density depends on the mass of the molecule and the degree of compaction between molecules. Through accurate density measurement experiments, the density value at a specific temperature can be known, which is of great significance for considering the phase behavior of the compound in the mixed system.
In addition, the boiling point of the compound also has characteristics. The boiling point reflects the energy required for the molecule to break away from the liquid state and transform into the gaseous state, which is closely related to the intermolecular forces. Under appropriate pressure conditions, the determination of its boiling point can provide key parameters for its separation and purification processes.
The above physical properties are the basis for in-depth understanding of tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylic acid esters, which are widely used in organic synthesis, drug development and other fields.

Tert-butyl 6-amino-3,4-dihydroisoquinoline-2 (1H) -carboxylic acid ester, this physical property belongs to the category of organic synthesis. It is white to white solid, stable at room temperature, and can cause combustion in case of open flame and hot topic.
From the chemical structure analysis, the compound contains tert-butyl, amino group, dihydroisoquinoline ring and carboxylic acid ester group. The presence of tert-butyl increases its steric resistance, affects intermolecular interactions, and also affects solubility, such as in non-polar organic solvents. The amino group is alkaline and can participate in acid-base reactions, form salts with acids, and is also a nucleophilic group. It can involve nucleophilic substitution, addition and other reactions, and is often a key reaction check point in organic synthesis. The dihydroisoquinoline ring system endows the molecule with a rigid structure, which affects the overall configuration and electron cloud distribution. The part of the aromatic ring has certain aromatic properties, and can undergo aromatic ring-specific reactions, such as electrophilic substitution. The carboxylic acid ester group is active, and can be hydrolyzed, alcoholyzed, and aminolyzed. Hydrolysis can be carried out under acid-base conditions. It is reversible when acid catalyzed, and irreversible when alkali catalyzed. Alcoholysis forms new esters, and amide is obtained when ammonysis.
Its melting point, boiling point and other physical parameters are of great significance for separation Accurate melting point data help determine purity, and boiling point information is indispensable in distillation and separation. In addition, its solubility characteristics provide a basis for selecting appropriate reaction solvents and separation media. For example, in organic synthesis, phase matching solvents are selected according to solubility to promote the smooth progress of the reaction and improve the yield.

In the Guanfu market, there are many kinds of materials, and the prices are different. However, it is not easy to know the price of tert - Butyl 6 - Amino - 3,4 - Dihydroisoquinoline - 2 (1H) - Carboxylate.
This compound is in the field of chemical industry, or it is an essential material. The determination of its price is related to many ends. First, the resources of raw materials. If the raw materials are not easy to obtain, difficult to harvest, and difficult to make, the price will be high. For example, the rare ore, the deep mountain to find, and the complex order to refine, its price will be high. If the raw materials of this compound are the same, how can the price be low?
Second, the method of preparation. If its production method is exquisite, it requires high-end equipment and good skills, and the cost of human and material resources is very large, its price will also increase. It is like a clever craftsman making utensils, meticulously crafted, and the working hours are long, and the price of utensils will be expensive.
Furthermore, the supply and demand of the city. If there are many people who want it, but there are few people who supply it, the so-called "rare things are expensive", and the price must be raised. If there are few users and too many products, the price may drop.
In addition, the difference in region also affects the price. Prosperous cities, with convenient logistics and many commercial ports, the price may be stable; remote places, with inconvenient transportation and difficult transshipment, the price may fluctuate.
However, I have searched all over the genus of "Tiangong Kaiwu" in the past, but I have not found the exact price of this object. In today's world, although the information is smooth, if you want to know the real-time price, you still need to consult the chemical industry or explore the professional market. The market conditions are ever-changing, and the price is uncertain, or you need to seek it yourself to get it.
