The synthesis of 6-amino-2-Boc-3,4-dihydro-1H-isoquinoline involves a variety of approaches. First, a palladium-catalyzed coupling reaction can be initiated by a suitable aromatic halide and an enamine derivative. In this reaction, palladium catalysts, such as palladium acetate, should be carefully selected with suitable ligands, such as tri-tert-butylphosphine, to help improve the efficiency and selectivity of the reaction. The reaction conditions also need to be carefully regulated, the temperature should be in a moderate range, such as 80-100 ° C, and it needs to be carried out in an inert gas atmosphere to avoid side reactions such as oxidation.
Furthermore, the cyclization strategy can be used. Linear precursors containing specific functional groups, such as compounds with amino and alkenyl groups, are first prepared, and then nucleophilic substitution or cyclization addition reactions are used in the molecule to promote the construction of isoquinoline rings.

6 - Amino - 2 - Boc - 3,4 - Dihydro - 1H - Isoquinoline is a very important compound in the field of organic synthesis. However, its market price is difficult to sum up. Due to the influence of many factors, its price fluctuates.
The first to bear the brunt is the cost of raw materials. The synthesis of this compound requires specific starting materials. If the supply of raw materials is scarce, or its acquisition cost is high, the price of the product will rise. For example, if the starting material relies on a special extraction process, or the origin is limited, the supply is tight, which will increase the cost and push up the market price.
Secondly, the simplicity of the synthesis process is also the key. If there are many synthesis steps, precise reaction conditions and special catalysts are required, and the reaction equipment is strictly required, all these factors will increase the production cost. Complex processes may require higher technical standards and professional equipment, and the investment of manpower and material resources will increase, which will naturally be reflected in the product price.
Furthermore, the market supply and demand relationship also affects its price. If the market demand for the compound is strong and the supply is relatively insufficient, the merchant will take advantage of the trend to raise the price; conversely, if the market demand is low and the supply exceeds the demand, the price will be under pressure to decline. For example, the pharmaceutical industry has a large increase in demand for it, and manufacturers have difficulty meeting the market for a while, so prices are easy to rise; if the research and development heat decreases during a certain period, the demand decreases, and the price may fall.
In addition, the scale of production also has an impact. In large-scale production, due to the scale effect, the unit production cost may be reduced, and the price will tend to be reasonable. On the contrary, in small-scale production, the fixed cost is allocated to the unit product more, and the price will be relatively high.
According to Guanfu's "Tiangong Kaiwu", although this compound did not exist at that time, the concept of "expensive grains but cheap gold and jade" is also similar to the principle of today's market price. The price of a product depends on the difficulty of production and the amount of demand. Today's 6 - Amino - 2 - Boc - 3,4 - Dihydro - 1H - Isoquinoline, according to this reason, its market price is in dynamic changes due to factors such as raw materials, process, supply and demand, scale, etc. It is difficult to give an exact value.

6-Amino-2-Boc-3,4-dihydro-1H-isoquinoline is an important intermediate commonly used in organic synthesis. Its storage conditions are crucial to the stability and activity of this substance.
This substance should be stored in a cool, dry and well-ventilated place. If it is cool, the temperature should not be too high, and the high temperature will easily cause chemical reactions such as decomposition and deterioration, which will damage its quality. Therefore, it is better to place it in a refrigerated environment with a temperature of about 2-8 ° C. This can effectively slow down the thermal movement of molecules, reduce the rate of chemical reactions, and maintain the stability of its chemical structure.
Dry environment is also indispensable. Moisture in the air may react with the substance such as hydrolysis, destroying its chemical composition. Therefore, moisture-proof measures need to be taken, such as storing it in a sealed container, and a desiccant can be placed in the container to absorb water vapor that may invade and keep it dry.
Furthermore, good ventilation can avoid the local accumulation of excessive volatile substances and prevent potential explosions or other safety risks. At the same time, avoid contact with oxidants, acids, alkalis and other substances. Because of their active chemical properties, coexistence with such substances can easily lead to violent chemical reactions, causing substance failure or danger.
When storing this substance, the label should clearly mark its name, specifications, storage conditions and valid period and other key information for easy management and use, and regularly check its appearance, purity and other indicators to ensure its quality. In this way, 6-amino-2-Boc-3,4-dihydro-1H-isoquinoline can be properly stored, so that it can play its due role in organic synthesis and other fields.
