This is the name of an organic compound. Its structure is complex and needs to be analyzed by chemical knowledge. "5 - Oxohexahydrocyclopenta [c] pyrrole - 2 - carboxylic acid tert - butyl ester", according to chemical nomenclature, "5 - Oxo" refers to the carbonyl group at the 5th position; "hexahydro" means that six hydrogen atoms on the ring are reduced; "cyclopenta [c] pyrrole" means that this is the parent nucleus of the cyclopentopyrrole-containing structure; "2 - carboxylic acid" has a carboxyl group at the 2nd position; "tert - butyl ester" means that this carboxyl group forms an ester group with tert-butyl group.
Described in the style of the ancient prose of "Tiangong Kaiwu", the compound seems to be described as: "In the parent nucleus of cyclopentopyrrole, after the reduction state of hexahydro, its pentacarbonyl, dicarbonyl and tert-butyl are combined into esters. This structure is exquisite, like the micro-matter of heaven and earth, which integrates all chemical elements, each in its own place, and coforms this organic shape. Its carbonyl is based on five bits, like a pearl embedded in a specific place of a pavilion, which shines brightly; tert-butyl ester, like the accessory of a pavilion, complements the main structure, resulting in this unique chemical structure."
In this way, the chemical structure of this compound is described in ancient Chinese, which may allow the viewer to imagine its delicate state. Although its chemical essence cannot be fully realized, it can also glimpse the complexity and uniqueness of its structure.

5 - Oxohexahydrocyclopenta [c] pyrrole - 2 - carboxylic acid tert - butyl ester is an organic compound, and its synthesis method is very particular. I can describe one or two common methods.
One is to use a specific cyclic compound as the starting material. First, take a cyclopentene derivative with a suitable substituent and react with a nitrogen-containing nucleophile under specific reaction conditions. For example, this cyclopentene derivative is mixed with a reagent such as acetamide in a base-catalyzed environment and stirred at an appropriate temperature. The base can be selected from potassium carbonate or the like, and the temperature can be controlled between 50 and 80 degrees Celsius. After a few times, the nucleophile can attack the specific position of the cyclopentene to form the preliminary structure of the nitrogen-containing heterocyclic ring. < Br >
Thereafter, the resulting product is carbonylated. Carbon monoxide gas is introduced and a suitable metal catalyst, such as palladium catalyst, is reacted in an organic solvent in the presence of suitable ligands. The organic solvent can be selected from dichloromethane, etc., and the reaction temperature may be 30-60 degrees Celsius to form a carbonyl group. This carbonyl group is the basis for the 5-oxo structure of the target product.
Furthermore, carboxyl protection and esterification are carried out. Using tert-butyl alcohol as the esterification reagent, the carboxyl group of the preliminary product is esterified under the condition of acid catalysis to form the tert-butyl ester structure. The acid can be selected as p-toluenesulfonic acid, and the reaction is carried out at a suitable temperature such as 60-80 degrees Celsius. After a few hours, the target 5-Oxohexahydrocyclopenta [c] pyrrole-2-carboxylic acid tert-butyl ester can be obtained.
Another synthesis method is to start from the precursor containing the pyrrole ring. First modify the pyrrole ring, introduce suitable substituents, and introduce halogen atoms at specific positions in the pyrrole ring through halogenation. Then use metal-organic reagents, such as Grignard reagents, to react with halogenated pyrrole to construct the basic skeleton of cyclopentene-pyrrole. The next steps are similar to the above, the carbonyl group is introduced through the carbonylation reaction, and then the carboxylic group is protected and esterified, and the final product is obtained. This synthesis method requires fine control of the reaction conditions and attention to the details of each step to effectively obtain the target 5 - Oxohexahydrocyclopenta [c] pyrrole - 2 - carboxylic acid tert - butyl ester.

Tert-butyl 5-oxo-hexahydrocyclopenta [c] pyrrole-2-carboxylate, an organic compound. Its physical properties are of great interest.
Looking at its morphology, under room temperature and pressure, it is mostly in the shape of a solid state, or a white to off-white crystalline powder, uniform and delicate, just like the coagulated jade, pure and simple.
As for the melting boiling point, the melting point is about [X] ° C, which is like a temperature boundary marker. At this temperature, its solid structure begins to disintegrate and gradually changes to a liquid state; the boiling point is about [X] ° C under specific pressure conditions. At that time, the intermolecular force is difficult to bind, and the substance turns into a gaseous state.
Solubility is also a key property. This substance has good solubility in common organic solvents such as dichloromethane and chloroform, just like fish getting water, and can be evenly dispersed in it. In solvents such as ethanol and acetone, it also has a certain solubility, but it is slightly inferior to the above solvents. In water, the solubility is very small. Due to its molecular structure characteristics, the affinity with water is not good, just like the difficulty of oil and water. < Br >
In terms of density, it is about [X] g/cm ³, which is similar to the density of common organic compounds. This value determines its position in the mixture, just like the "weight label" of the object.
In addition, the compound has certain stability. Under normal storage conditions, in a dry and cool place, it can maintain its own structure and properties relatively stable. In case of extreme conditions such as strong acids and bases, chemical reactions may occur, and the structure will be broken and the properties will also change.

I look at your question, but I am inquiring about the market price of 5 - Oxohexahydrocyclopenta [c] pyrrole - 2 - carboxylic acid tert - butyl ester. However, the market price of this substance, the inter-market price state, often depends on the quality, source, supply and demand conditions vary, and it is difficult to determine the value.
If it is in the chemical raw material market, the ordinary quality, or purchased by suppliers, the price may vary according to the quantity. A small amount is purchased, ranging from tens of yuan to hundreds of yuan per gram; if it is purchased in batches, the larger the quantity, the lower the price per gram, or down to tens of yuan per gram.
Or in the scientific research reagent market, its requirements for quality purity are quite high, and the price is also higher. High-purity products, per gram or more than 100 yuan, or even up to hundreds of yuan per gram.
And cities in different regions, due to logistics and tax differences, the price is also different. In busy commercial ports, logistics is convenient, and the price may be slightly flat; in remote places, due to high transportation costs, the price may be slightly high.
There is a trend of market supply and demand. If there are many applicants and few suppliers, the price will rise; on the contrary, if the supply exceeds the demand, the price may drop. Therefore, if you want to know the exact price, you need to consult chemical raw material suppliers, scientific research reagent merchants, or check on relevant trading platforms to get a near real-time price.
