What are the synthesis methods of methyl 2-amino-6-methyl-4,5,6, 7-tetrahydro-1-benzothiophene-3-carboxylate

The synthesis of methyl 2-amino-6-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylic acid esters has many paths to follow.

First, sulfur-containing aromatics can be initiated. First, the sulfur-containing aromatics and haloalkanes are alkylated in the presence of suitable bases and solvents, and alkyl groups such as methyl are introduced into the aromatic ring. Then, with the help of specific electrophilic reagents, electrophilic substitution occurs at specific positions in the aromatic ring to construct the thiophene ring part. At this time, the reaction conditions, such as temperature, reagent ratio, etc., need to be precisely adjusted to ensure that the thiophene ring is constructed at the desired position. Subsequently, the carboxyl group is introduced at the appropriate check point of the thiophene ring, which can be reacted with carbon dioxide by Grignard reagent or achieved by other carboxylation methods. Finally, the carboxyl group is converted to the methyl ester group, and the common method is to esterify with methanol under the action of acid catalyst. At the same time, the amino group can be introduced at the designated position by suitable amination reagents.

Second, it can also start from thiophene derivatives. The thiophene derivative is first hydrogenated to achieve the construction of the 4,5,6,7-tetrahydrogen structure. This step requires the selection of an appropriate catalyst, such as a metal catalyst, to control the reaction pressure and temperature to ensure that the hydrogenation reaction occurs precisely at the desired double bond position. After that, according to the above-mentioned similar method, methyl and carboxyl groups are introduced and converted into methyl ester groups in sequence, and amino groups are introduced.

Furthermore, it is also feasible to use benzothiophene compounds as raw materials. The tetrahydro structure can be formed by selectively reducing part of the double bond of benzothiophene. Then, a series of substitution reactions are used to introduce methyl, amino and carboxyl ester groups necessary for the target molecule one by one. During the entire synthesis process, each step of the reaction needs to be carefully controlled, and the reaction intermediates are strictly separated and identified to ensure that the final product is pure methyl 2-amino-6-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate.

What are the precautions in the preparation of methyl 2-amino-6-methyl-4,5,6, 7-tetrahydro-1-benzothiophene-3-carboxylate

When preparing methyl 2-amino-6-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylic acid ester, there are many urgent things to pay attention to.

First, the selection and quality of raw materials are crucial. The selected raw materials must be pure, and if there are many impurities, it will affect the purity and yield of the product. Just like craftsmen creating utensils, if the initial materials are poor, the finished product will not be a high-quality product. The storage of raw materials must also be proper, moisture-proof, oxidation-proof, etc., otherwise its properties will change and the reaction will be difficult to achieve expectations.

Second, the reaction conditions need to be precisely controlled. In terms of temperature, either too high or too low is not good. If the temperature is high, the reaction may be out of control and side reactions will increase; if the temperature is low, the reaction rate will be slow, time-consuming, and even incomplete. Just like cooking, if the heat is not appropriate, the dish will lose its taste. The reaction time should also be just right. If it is too short, the reaction will not be completed, and if it is too long, it will cause product decomposition or overreaction.

Third, the choice of solvent should not be ignored. Different solvents have an impact on the solubility, reaction rate, and selectivity of the reaction. Choosing the right solvent is like setting a solid stage for the reaction to make the reaction proceed smoothly.

Fourth, the operation process must be rigorous. The feeding sequence should not be wrong, and the stirring should be uniform to ensure that the reactants are in full contact. And the reaction equipment should be clean to avoid < Br >
Fifth, product separation and purification are also critical. Crude products often contain impurities, and appropriate methods such as recrystallization and column chromatography need to be used to purify to obtain high-purity products, just like panning gold in sand, removing voids and storing cyanine.
