methyl 2-amino-4-(4-tert-butylphenyl)thiophene-3-carboxylate

Methyl-2-amino-4- (4-tert-butylphenyl) thiophene-3-carboxylic acid ester, this is a kind of organic compound. Looking at its name, its structure can be deduced according to the nomenclature of organic chemistry.
"Methyl" is an alkyl group of one carbon, that is, -CH
. It can be seen that there is this group in the molecule. "2-amino", epiamino-NH < 2 is attached to the No. 2 position of the thiophene ring. " 4 - (4 -tert-butylphenyl) ", which means that the 4th position of the thiophene ring is connected with a phenyl group, and the 4th position of the phenyl group is connected with a tert-butyl group, and the tert-butyl group is -C (CH < unk >) < unk >." Thiophene-3 -carboxylate "indicates that the 3rd position of the thiophene ring is connected with a carboxylate group, that is, -COOCH < unk > (because there is" methyl "at the beginning, it is a methyl ester group).
In general, the structure of this compound consists of a thiophene ring as the core, with an amino group at position 2, a methyl ester group at position 3, and a 4-tert-butylphenyl group at position 4. Its structure is: on the thiophene ring, each substituent is arranged in sequence, showing a specific spatial and chemical connection mode. This structure endows the compound with unique physical and chemical properties, which may be used in organic synthesis, pharmaceutical chemistry and other fields.

Methyl-2-amino-4- (4-tert-butylphenyl) thiophene-3-carboxylic acid ester, having various physical properties. Its appearance is often white to light yellow powder, which is common in many organic compounds due to the atomic arrangement and electron cloud distribution in the molecular structure.
As far as the melting point is concerned, it is about a specific temperature range, due to the intermolecular forces. There are hydrogen bonds, van der Waals forces, etc., which interact to maintain the orderly arrangement of molecules. When heated to a certain extent, these forces are overcome, and the substance is melted from a solid state to a liquid state.
Solubility is also an important physical property. In organic solvents such as dichloromethane and chloroform, it exhibits good solubility because the molecular structure of the compound and the molecules of the organic solvent can form similar intermolecular forces, following the principle of "similar phase dissolution". However, in water, the solubility is not good, and the hydrophobic part of the molecule accounts for a large proportion, making it difficult to form effective interactions with water molecules.
In addition, the density of the compound is also a certain value, reflecting its mass per unit volume, which is related to the relative molecular mass of the molecule and the degree of intermolecular packing. In the solid state, the degree of molecular arrangement affects the density. The volatility is relatively low, which is due to the strong intermolecular forces, and the molecules are not easy to break free from each other and enter the gas phase. In summary, the physical properties of methyl-2-amino-4- (4-tert-butylphenyl) thiophene-3-carboxylic acid esters are determined by their molecular structure, and these properties play a key role in various chemical processes and applications.

The synthesis of methyl 2-amino-4- (4-tert-butylphenyl) thiophene-3-carboxylic acid esters is an important topic in the field of organic synthesis. The synthesis route can vary depending on different starting materials and reaction conditions.
First, it can be started from thiophene derivatives containing specific substituents. First, the thiophene ring is suitably substituted to introduce tert-butylphenyl. In this step, halogenated aromatics and thiophenes are usually coupled under metal catalysis, such as the Suzuki coupling reaction catalyzed by palladium. Halogenated thiophene and 4-tert-butyl halobenzene can effectively form carbon-carbon bonds under the action of alkali and palladium catalysts to obtain 4- (4-tert-butylphenyl) thiophene derivatives.
Then, the obtained product is carboxylated. Carboxyl groups can be introduced at specific positions in the thiophene ring by metal-organic reagents, such as Grignard reagent or lithium reagent, and carbon dioxide can be used to react with carbon dioxide, followed by esterification reaction, and methanol is catalyzed to form esters under acid to obtain methyl 4- (4-tert-butylphenyl) thiophene-3-carboxylic acid esters.
Furthermore, amino group introduction step. The above-mentioned esters can be aminated by suitable amination reagents. It is common to replace the suitable leaving group on the thiophene ring with ammonia or primary amine under appropriate reaction conditions to achieve the introduction of amino groups, and finally obtain the target product methyl 2-amino-4- (4-tert-butylphenyl) thiophene-3-carboxylate.
Another idea is to construct a thiophene ring first. Using raw materials containing amino groups, carboxyl groups and tert-butylphenyl groups, etc., the thiophene ring is constructed by cyclization reaction. If β-ketoate, amine and aldehyde containing tert-butylphenyl are used as raw materials to form thiophene ring through multi-step reaction, the reaction conditions need to be finely regulated during the process to ensure the correct introduction of each group and the selectivity of the reaction check point, and the synthesis of the target product can also be achieved.
