ethyl 2-(methylsulfanyl)quinoline-1(2H)-carboxylate

This is an inquiry about the chemical structure of "ethyl 2- (methylsulfanyl) quinoline-1 (2H) -carboxylate". According to chemical nomenclature, "ethyl" is ethyl, indicating that the compound contains ethyl groups; "2- (methylsulfanyl) " means that there is a methylsulfanyl at the 2nd position, and "methylsulfanyl" is methylsulfanyl-SCH; "quinoline" is a quinoline ring, which is a nitrogen-containing heterocyclic aromatic hydrocarbon; "1 (2H) -carboxylate" indicates that there is a carboxylic acid ester group at the 1st position (at the 2H position) of the quinoline ring. Overall, its chemical structure is based on the quinoline ring as the core, with a methylthio group at the 2nd position and a carboxylate ethyl group at the 1st position (at 2H). In this structure, the quinoline ring endows it with certain aromaticity and special electron cloud distribution, the methylthio group is the power supply group, which may affect the electron density and reactivity of the molecule, and the carboxylic acid ethyl ester group can participate in a variety of organic reactions, such as hydrolysis, alcoholysis, etc. In this way, the chemical structure of this compound is clarified.

Ethyl-2- (methylthio) quinoline-1 (2H) -formate, this substance is an organic compound. Looking at its structure, it is composed of quinoline ring system, methylthio group and ethyl formate group.
In terms of its physical properties, under normal temperature, or in a solid state, it is mostly due to the interaction between organic molecules, so that it has a certain lattice structure. Its melting point and boiling point belong to the strength of intermolecular forces. Intermolecular forces contain van der Waals forces, hydrogen bonds, etc. Because the molecule contains aromatic rings and polar groups, Van der Waals forces are strong, so the melting point, boiling point or at a certain range.
In terms of solubility, the compound may have different behaviors in organic solvents. It has a certain polarity, so it may have better solubility in polar organic solvents such as ethanol and acetone. The interaction between polar solvents and the polar groups of compounds can reduce the energy of the system and promote dissolution. However, in non-polar solvents such as n-hexane, the solubility may not be good, because the force between the two is weak.
Appearance color, or white to light yellow powder or crystalline. Due to the different transition energy levels of electrons in the molecular structure, the absorption and reflection of visible light are different, so it shows this color.
Volatility is also one end of its physical properties. Due to the limitation of intermolecular forces, the volatility is not high, and it is difficult to quickly evaporate to the gas phase at room temperature and pressure. The density of
may be different from that of water, or due to different molecular compositions and packing methods. Its density may be slightly higher than that of water, or less than that of water, depending on the specific molecular structure and atomic mass distribution.
The physical properties of ethyl-2- (methylthio) quinoline-1 (2H) -formate are the basis for its application in chemical industry, medicine and other fields, and are of great significance to the research and production of related fields.

To prepare ethyl 2- (methylsulfanyl) quinoline-1 (2H) -carboxylate, the method of organic synthesis is often followed. At the beginning, the appropriate quinoline derivative is used as the base. Or take quinoline first, make it under specific reaction conditions, and introduce a group containing methyl sulfide at the 2-position. This can be done by means of a nucleophilic substitution reaction. Select a suitable methyl sulfide reagent, such as methyl mercaptan, and react with quinoline in the presence of a suitable solvent and base, so that the thio group is connected to the 2-position of quinoline.
Then, the carboxethyl ester group needs to be constructed at the 1 (2H) -position of quinoline. Or it can be activated by first activating the 1-position and then reacting with a reagent containing ethyl ester group. For example, the 1-position is first halogenated to obtain a halogenated quinoline derivative, and then with the help of ethanol and carbon dioxide in a metal catalyst (such as palladium catalyst), the carboxyl group is introduced by carboxylation reaction, and then esterified with ethanol to form this carboxyethyl ester group.
Or there is another way. A quinoline parent nucleus containing carboxyethyl ester group can be constructed first, and then a methyl thio group can be introduced. For example, a quinoline precursor containing ethyl ester group is introduced at the 2-position by electrophilic substitution reaction. This process requires good control of the reaction conditions, selection of suitable reaction reagents and catalysts, and attention to factors such as temperature and reaction time to promote the smooth reaction and obtain high-purity ethyl 2- (methylsulfanyl) quinoline-1 (2H) -carboxylate. The way of synthesis is more expensive than carefully choosing the path and carefully examining the conditions of each step of the reaction, so that each step can achieve the desired purpose and obtain sufficient and high-quality products.
