6,7-Difluoro-4-oxo-1-cyclopropyl-1,4-dihydro-quinoline-3-carboxylic acid

6,7-Diene-4-oxo-1-cyclopentyl-1,4-dicyclo-dioxide-3-heptanoenoic acid, which is an organic compound with unique chemical properties.
Its structure contains conjugated dienes, which endows the compound with active reactivity. The conjugated system makes the electron cloud delocalized and prone to addition reactions, such as the Diels-Alder reaction with the diene body, which can efficiently construct a six-membered ring structure and is widely used in the field of organic synthesis.
The 4-oxo functional group introduces polarity to the molecule, which affects the physical and chemical properties of the compound. The carbonyl group in the oxo group is electrophilic and can undergo nucleophilic addition reactions with nucleophiles, such as reacting with alcohols to form acetals or hemiacetals, and reacting with amines to form imines.
1-cyclopentyl group gives the molecule a certain rigidity and stereostructure, which affects its spatial conformation and reaction selectivity. The steric hindrance around the cyclopentyl group plays an important role in the reaction process and product configuration. In some reactions, the reaction in a specific direction may be inhibited or accelerated due to spatial hindrance.
1,4-Dioxide is also a key part of the bicyclic structure, which imparts molecular stability, and the presence of two oxygen atoms increases molecular polarity and reactivity check points. This structure may affect the solubility of molecules in different solvents, and plays an important role in redox reactions or other reactions involving electron transfer.
The 3-heptanoenoic acid part contains carboxyl groups, which are acidic and can be neutralized with bases to form corresponding carboxylic salts. At the same time, carboxyl groups can participate in esterification reactions and form ester compounds with alcohols under acid catalysis, which is of great significance for the preparation of ester derivatives with specific functions.
In summary, 6,7-diene-4-oxo-1-cyclopentyl-1,4-dicyclo-dioxy-3-heptanoenoic acid shows potential application value in organic synthesis, medicinal chemistry and other fields due to its special structure, and its diverse reactivity provides rich possibilities for the synthesis of complex organic molecules.

To prepare 6% 2C7-diene-4-oxo-1-cyclopentyl-1% 2C4-diethyl dicarbonate-3-carboxylic acid, the method is as follows:
The method of using cyclopentene derivatives as the starting material is first proposed. Cyclopentene can be reacted with a specific diene by Diels-Alder to construct a key carbon skeleton. This reaction condition is mild and the stereoselectivity is good, which can efficiently generate intermediates with specific configurations. The intermediate is then oxidized to introduce carbonyl groups. If a suitable oxidizing agent is used, the reaction at a suitable solvent and temperature will oxidize the specific position to carbonyl groups. Then through the esterylation reaction, the diethyl carbonate group is introduced, and the corresponding esterylation reagent and catalyst are selected to achieve in the appropriate reaction system. Finally, the other position is oxidized and the carboxyl group is introduced at the same time. After a series of reactions, the target product can be obtained.
There is also a method of using simple aliphatic compounds as starting materials. Through a multi-step carbon-carbon bond formation reaction, the cyclopentyl structure is gradually constructed. First, the carbon negative ion reaction is used to react with suitable halogenated hydrocarbons or carbonyl compounds to increase the carbon chain. Cyclopentane ring is constructed by cyclization reaction, and then the functional groups such as oxygen, diethyl carbonate and carboxyl are introduced in sequence through selective oxidation and esterification. Although this route is a little complicated, the raw materials are easy to obtain and have cost advantages.
Or it can learn from the idea of biomimetic synthesis. Simulate the relevant metabolic pathways or enzyme catalysis processes in living organisms, start from simple natural products or similar products, and use specific biological enzymes or biomimetic catalysts to react under relatively mild conditions. This approach is green and environmentally friendly, with high selectivity, and is expected to improve the purity and yield of the product. However, the reaction conditions and catalysts are strict and need to be carefully regulated.

I don't know what you mean by "6% 2C7-diene-4-oxo-1-cyclopentyl-1% 2C4-dioxobicyclo-3-heptanoenoic acid", but the price in the city often changes due to many reasons, such as origin, quality, season, supply and demand conditions, etc.
If this enoic acid is an ordinary chemical raw material, its price may vary according to purity and output. If the purity is high and the output is large, the price may be slightly lower; if the purity is thin and the output is rare, the price must be high.
The distance of the origin is also related to the freight, which in turn affects the price. If it is produced nearby, the price may be more affordable; if it is transported from a distance, the price may increase due to the freight.
The season is also an important reason. If it is in the peak production season, the supply exceeds the demand, and the price drops; if it is in the off-season, the supply exceeds the demand, and the price rises.
However, it is difficult for me to determine the specific price range, because there is no more detailed information. If you want to know the exact price, you can consult the merchants in the chemical raw material market, or check the professional chemical product quotation platform, in order to obtain an accurate number.

In the early days of the development of organic synthetic chemistry, German chemist Carl Duisberg focused on exploring new paths in organic synthesis and was very interested in the synthesis of compounds containing ring structures.

Although he did not directly synthesize this compound, his research on the mechanism of cyclization reaction pointed the way for subsequent chemists.
In the mid-20th century, American chemist Robert Burns Woodward was famous for his outstanding contributions to the total synthesis of complex organic molecules.
