6 - benzyl - 1,2,3,4,4a, 7a - hexahydropyrrolo [3,4 - b] pyridine - 5,7 - dione is an organic compound. Its physical properties are as follows:
In terms of concept, this substance may be a crystalline solid, because many similar compounds containing nitrogen heterocycles and carbonyl groups often appear in this state. When powdered, it is fine and uniform. Its color may be white to light yellow. Due to the influence of groups such as benzene rings in the molecular structure, if there is no special chromophore, it is mostly in this range of color.
When it comes to the melting point, although there is no exact literature to investigate, the melting point of nitrogen-containing heterocyclic diones with similar structures may be between 150 ° C and 250 ° C. Due to the existence of hydrogen bonds and van der Waals forces in the molecule, the interaction between molecules is strong, and higher temperatures are required to destroy the lattice.
In terms of solubility, in organic solvents, this compound may be slightly soluble in non-polar solvents such as petroleum ether and n-hexane, because its molecules contain polar carbonyl groups and nitrogen atoms, and the interaction with non-polar solvents is weak. In polar organic solvents such as methanol, ethanol, and dichloromethane, its solubility may be better. Taking methanol as an example, the solubility of the compound in methanol is increased by the formation of hydrogen bonds between carbonyl groups and methanol hydroxyl groups. In water, its solubility may not be good due to its limited polarity.
In addition, the density of the compound is also difficult to have an accurate value. However, according to its structure containing benzene rings and heterocycles, the relative molecular weight is large, and the molecular arrangement or tight, and the estimated density is greater than that of water.
In summary, 6-benzyl-1,2,3,4,4a, 7a-hexahydropyrrolo [3,4-b] pyridine-5,7-dione has specific physical properties and has unique applications in organic synthesis, pharmaceutical chemistry and other fields due to these properties.

6-Benzyl-1,2,3,4,4a, 7a-hexahydropyrrolido [3,4-b] pyridine-5,7-dione, this is an organic compound. Its chemical properties are unique and contain many interesting things.
First of all, in terms of its physical properties, due to its molecular structure containing benzyl and specific heterocycles and carbonyl groups, it may be in a solid state at room temperature. The solubility of this compound is influenced by molecular polarity. Benzyl is a non-polar group, while the pyridine ring and dione structure have a certain polarity, so it may have a certain solubility in non-polar solvents (such as benzene and toluene), but its solubility in polar solvents (such as water) may be limited.
In terms of its chemical properties, carbonyl poles are active. The carbonyl group at 5,7-diketone can participate in many chemical reactions. For example, it can undergo addition reactions with nucleophiles. Like alcohols, under specific conditions, or attack carbonyl carbons to generate hemiketal or ketal products. And because the molecule contains nitrogen heterocycles, the nitrogen atom has a lone pair of electrons, showing a certain alkalinity, which can react with acids to form salts.
Furthermore, the benzyl ring in the benzyl group has aromatic properties and can undergo electrophilic substitution reactions. If under the action of a suitable catalyst, it can react with halogenated hydrocarbons, acyl halides, etc., and introduce new substituents on the benzene ring. And the carbon-carbon double bond of the hexahydropyrrolido-pyridine ring can participate in the addition reaction, react with hydrohalic acid, halogen and other reagents to realize the conversion of functional groups.
In addition, there are multiple chiral centers in the compound, or optically active, isomers of different configurations, or differences in physical and chemical properties. The chemical properties of this compound make it potentially useful in organic synthesis, pharmaceutical chemistry and other fields.

To prepare 6-benzyl-1,2,3,4,4a, 7a-hexahydropyrrolido [3,4-b] pyridine-5,7-dione, the method is as follows:
First, use suitable starting materials, or compounds with specific structures, and carefully designed reaction pathways. Common starting materials, or related structural fragments containing pyridine, pyrrole, etc., can be used as a basis for the core structure of this target molecule.
One of the methods can be achieved by condensation reaction. Under suitable reaction conditions, such as selecting a good solvent, such as dichloromethane, N, N-dimethylformamide, etc., the reactants can be fully dissolved and the reaction can be carried out. And add an appropriate amount of catalyst, or an organic base, such as triethylamine, pyridine, or Lewis acid, such as zinc chloride, aluminum trichloride, etc., which can promote the occurrence of condensation reactions, make intermolecular bonding, and initially form the framework of pyrrolido [3,4-b] pyridine.
Then, hydrogenation reaction is carried out for the framework. The purpose of this step is to saturate the double bonds on the pyridine ring and the pyrrole ring to achieve the structure of 1,2,3,4,4a, 7a-hexahydro. Catalytic hydrogenation can be used, and metals such as platinum and palladium are selected to be supported on active carbon and other supports as catalysts. In a hydrogen atmosphere, the appropriate temperature and pressure are controlled. Generally, the temperature is between room temperature and tens of degrees Celsius, and the pressure is in the range of several atmospheres, so that the double bonds can be hydrogenated smoothly to obtain the required hexahydro structure.
As for the introduction of benzyl, it can be used in the product after hydrogenation to benzylation reagents, such as benzyl halide (benzyl chloride, benzyl bromide, etc.), under basic conditions, such as potassium carbonate, sodium hydroxide, etc. In the presence of bases, nucleophilic substitution occurs, so that the benzyl is attached to a specific position of the target molecule, resulting in 6-benzyl-1,2,3,4,4a, 7a-hexahydropyrrolido [3,4-b] pyridine-5,7-dione. Each step of the reaction requires fine control of the reaction conditions and monitoring of the reaction process to achieve high yield and high purity products.

I am looking at your words, but I am inquiring about the price range of 6 - benzyl - 1,2,3,4,4a, 7a - hexahydropyrrolo [3,4 - b] pyridine - 5,7 - dione in the market. However, this is not a common thing I am familiar with, and the price between markets is also affected by many factors, such as origin, purity, supply and demand, time and place of transaction, etc.
If the price is checked, the origin is different, the cost of materials and transportation costs are different, and the price is also different. The higher the purity, the more difficult it is to prepare, and the price may be higher. When the supply exceeds the demand, the price may decline; when the supply exceeds the demand, the price may rise. And at different times and places, the market conditions are different, and the price is also different.
Although it is difficult for me to determine the price range, if you want to know the details, you can go to the market where chemical reagents are traded, consult merchants, or visit professional chemical product trading platforms, and search for their prices with the convenience of the Internet. Or negotiate with people in the chemical industry, who may know the approximate price due to their experience in the industry. In this way, a relatively accurate price range can be obtained.
