tert-butyl 4,5-dihydro-1H-pyrazolo[3,4-c]pyridine-6(7H)-carboxylate

This is a problem of structural analysis of chemical substances. The structure of 4,5-dihydro-1H-pyrrolido [3,4-c] pyrrole-6 (7H) -ketone carboxylic acid can be derived step by step from its naming.
The concept of its naming, "pyrrole [3,4-c] pyrrole", indicates that the core structure of the substance is formed by the fusing of two pyrrole rings, and the fusing method is based on the [3,4-c] rule, which means that the two pyrrole rings are connected and fused with specific atoms.
"4,5-dihydro", revealing hydrogenation on the carbon-carbon double bonds at positions 4 and 5, that is, the two original unsaturated bonds become single bonds.
"1H -" indicates that the hydrogen atom at position 1 is in a specific position.
"6 (7H) -keto" means that there is a carbonyl group (C = O) on the carbon atom at position 6, and the hydrogen atom at position 7 is in the corresponding position.
"Carboxylic acid" indicates the presence of a carboxyl (-COOH) functional group in the molecular structure.
Based on the above information, the chemical structure of this substance is based on the fusing of two pyrrole rings, with saturated single bonds at positions 4 and 5, carbonyl at position 6, hydrogen atom at position 7, and carboxyl groups. In this way, the chemical structure of 4,5-dihydro-1H-pyrrole [3,4-c] pyrrole-6 (7H) -ketone carboxylic acid is constructed.

To prepare furyl-4,5-dihydro-1H-pyrrolido [3,4-c] pyrrole-6 (7H) -carboxylic acid amides, there are various methods.
First, suitable starting materials can be found, and they can be converted through multiple steps. For example, first take a compound with a specific structure, perform a nucleophilic substitution reaction, carefully adjust the reaction conditions, such as temperature, solvent, catalyst, etc., so that the reactants can be combined according to a predetermined path to form a key intermediate. Then, the cyclization reaction of the intermediate is ingeniously carried out, or catalyzed by acid-base catalysis, or by heating, etc., to promote the rearrangement and cyclization of atoms in the molecule to obtain a product containing the target ring system. Then modified, such as introducing specific functional groups at suitable check points, to achieve the structural requirements of the target product.
Second, you can try the method of biomimetic synthesis. Many biosynthetic processes in nature are exquisite and can draw inspiration from them. Simulate the relevant enzymatic reaction mechanism in vivo, and build target molecules with high selectivity with the help of mild reaction conditions. Find biomimetic catalysts with similar catalytic activity, or simulate the microenvironment in vivo, so that the reaction can be carried out efficiently and accurately, reduce the occurrence of side reactions, and improve product purity and yield.
Third, the strategy of combinatorial chemistry can also be considered. Using basic modules of different structures as raw materials, through systematic arrangement and combination, multiple sets of reactions can be carried out in parallel. Using high-throughput screening technology to quickly identify products with target structure or activity. This strategy can greatly shorten the R & D cycle, broaden the diversity of the compound library, and provide more possibilities for obtaining furyl-4,5-dihydro-1H-pyrrole-6 (7H) -carboxylic acid amides and their analogs.

Fu 4,5-dihydro-1H-pyrrole [3,4-c] pyrrole-6 (7H) -one derivatives are a class of organic compounds with considerable characteristics. Its physical properties are multi-faceted.
Looking at its appearance, it is usually a crystalline solid, which is caused by the regular arrangement of intermolecular forces. The crystalline form may be needle-like or flake-like, which varies depending on the specific structure and crystallization conditions. Its color is usually white to light yellow, and the higher the purity, the lighter the color.
When it comes to melting point, the melting point of such compounds is relatively high, mostly in a certain temperature range. There are interactions between conjugated systems and hydrogen bonds in the caine molecule, which make the molecules bond tightly. High energy is required to destroy the lattice structure and realize the transition from solid to liquid.
In terms of solubility, the solubility varies from organic solvents. In polar organic solvents, such as methanol and ethanol, or have a certain solubility. Some polar groups in the molecule can interact with polar solvent molecules to form hydrogen bonds, etc., to promote dissolution. However, in non-polar solvents, such as n-hexane and toluene, the solubility is low, because the overall polarity of the molecule is limited, and the force with non-polar solvent molecules is weak.
In addition, its density is also one of the physical properties. Although it is different due to the specific structure, its density is usually similar to that of common organic compounds. And such compounds are relatively stable under normal temperature and pressure, but under specific conditions, such as high temperature, strong acid and alkali environment or specific catalyst, various chemical reactions can occur, which are also related to their physical properties.

Looking at your inquiry about the market price of "furyl 4,5-dihydro-1H-pyrrolido [3,4-c] pyrrole-6 (7H) -carboxylate", I am here for you.
However, as far as I know, the price of this product often varies for multiple reasons. The first one is the difficulty of preparation. The synthesis of this compound may require exquisite skills and complicated steps. The raw materials used may be rare or expensive, and the preparation is time-consuming and labor-intensive. If the raw materials are easy to obtain and the process is simple, the price may be slightly easier.
Furthermore, the state of market supply and demand is also the key. If there is a high demand for this product in the fields of medicine, chemical industry, etc., but the supply is limited, the so-called "rare is expensive", the price will be high; on the contrary, if the demand is low and the supply is sufficient, the price will tend to decline.
In addition, the difference between the place of production and the quality also affects the price. In different places, due to the difference in manpower, material resources, and taxes, the cost is different and the price is also different. Those with excellent quality may have higher prices than ordinary products.
However, it is difficult for me to determine the specific price. The market situation changes, and the price fluctuates from time to time.
