Furo[2,3-c]pyridine-6(5H)-carboxylicacid, 4,7-dihydro-, 1,1-dimethylethyl ester

"Furo [2,3-c] pyridine-6 (5H) -carboxylic acid, 4,7-dihydro-1,1-dimethylethyl ester", this name contains many key information.
"Furo [2,3-c] pyridine", it can be known that its core structure is the furan-pyridine ring system, and the furan ring and the pyridine ring are fused in a specific way, that is, the [2,3-c] way. " 4,7-dihydro - "indicates that hydrogen atoms participate in the reaction at the 4,7 positions, resulting in the hydrogenation and reduction of the partially unsaturated bond of the ring system." -6 (5H) -carboxylic acid "indicates that a carboxylic acid group is connected at the 6 position (considering the 5H state). And" 1,1-dimethylethyl ester ", that is, tert-butyl ester, indicates that the carboxylic acid and tert-butyl alcohol are esterified to form the corresponding ester structure.
In summary, the chemical structure of this compound is based on furanopyridine as the parent nucleus, dihydro state at the 4,7 positions, and tert-butyl carboxylic acid group at the 6 positions. In this way, its chemical structure can be understood.

This is 4,7-dihydrofurano [2,3-c] pyridine-6 (5H) -carboxylic acid-1,1-dimethyl ethyl ester. Its physical properties are as follows:
Looking at its properties, it is often white to off-white solid. Due to the regular arrangement of atoms and groups in the molecular structure, the intermolecular forces are stable, and most of them exist in the solid state.
When it comes to the melting point, it is about a specific temperature range. Due to the fixed intermolecular forces, a certain amount of energy is required when heated to destroy the lattice structure and convert it from solid to liquid. This melting point characteristic is crucial for identifying and purifying this substance.
As for solubility, it has a certain solubility in organic solvents such as dichloromethane, chloroform, and N, N-dimethylformamide. Because its molecular structure contains specific functional groups, it can form interactions with organic solvent molecules such as hydrogen bonds and van der Waals forces, so it is soluble. However, the solubility in water is not good, because the overall hydrophobic tendency of the molecule is strong, the force between water molecules and solute molecules is difficult to match the force between solute molecules, so it is not easily soluble.
And its density also has a specific value, reflecting the degree of tight accumulation of molecules, which is related to molecular structure and quality. Density characteristics are of great significance in chemical production and separation processes. The physical properties of this compound are closely related to its molecular structure, and are a key consideration in the fields of synthesis and application, assisting researchers and producers in making good use of it.

To prepare Furo [2,3 - c] pyridine - 6 (5H) -carboxylic acid, 4,7 - dihydro -, 1,1 - dimethylethyl ester, the following method can be followed.
First, select the appropriate starting material. The compound containing the corresponding pyridine and furan structures is used as a base, and this structure needs to have a modifiable check point so that the desired functional groups and groups can be introduced into the subsequent reaction.
Then, hydrogenation is performed to achieve the purpose of 4,7 - dihydro. Select the appropriate hydrogenation conditions, such as the appropriate catalyst, such as palladium carbon, etc., to control the temperature, pressure and reaction time of the reaction, so that the 4,7 positions of the pyridine ring can be successfully hydrogenated.
Furthermore, the esterification reaction is carried out to introduce 1,1-dimethylethyl ester group. 1,1-dimethylethanol and the corresponding carboxylic acid can be selected. Under the condition of acid catalysis or the presence of a condensing agent, such as concentrated sulfuric acid as the catalyst or DCC (dicyclohexyl carbodiimide), the esterification reaction between the two occurs to form the target ester.
During the reaction, the reaction process needs to be closely monitored. The method of thin layer chromatography (TLC) can be used to observe the consumption of raw materials and the formation of products. If side reactions occur, the reaction conditions need to be adjusted in a timely manner, such as changing the temperature, the proportion of reactants, etc., to inhibit side reactions and improve the yield of the target product.
The reaction is completed, and the steps of separation and purification are carried out. Column chromatography, recrystallization and other means can be used to separate the target product from the reaction system, remove impurities, and obtain pure Furo [2,3 - c] pyridine - 6 (5H) -carboxylic acid, 4,7 - dihydro -, 1,1 - dimethylethyl ester.
