methyl 2,4,5-trimethyl-1H-pyrrole-3-carboxylate

Methyl-2,4,5-trimethyl-1H-pyrrole-3-carboxylic acid ester, its chemical structure is as follows.
This compound belongs to pyrrole derivatives, with a pyrrole five-membered nitrogen-containing heterocyclic core structure. In the 1H-pyrrole ring, the hydrogen on the nitrogen atom is unsubstituted and maintains the 1H form. The 2, 4, and 5 positions are each connected with a methyl group, namely -CH, which alters the electron cloud distribution and steric hindrance of the pyrrole ring. The 3-position is connected with a carboxylic acid ester group -COOCH, which is composed of carbonyl-C = O and methoxy-OCH. The carbon-oxygen double bond in the carbonyl group is positive and vulnerable to attack by nucleophiles. The oxygen in the methoxy group contains lone pairs of electrons, which have an electronic effect on the carbonyl group. The pyrrole ring has certain aromaticity due to the existence of nitrogen atoms, and the electron cloud distribution is not uniform due to the nitrogen electronegativity and ring substituents. This structure endows the compound with specific physicochemical properties and reactivity, and may have applications in organic synthesis, pharmaceutical chemistry and other fields.

The synthesis method of methyl-2,4,5-trimethyl-1H-pyrrole-3-carboxylic acid esters is an important topic in the field of organic synthesis. The synthesis method can be traced back to the research of many parties in the past.
In the past, there were those who used specific nitrogen-containing heterocyclic compounds as starting materials. The starting material meets the carboxylic acid derivative with a specific substituent group. Under suitable reaction conditions, such as adding a specific catalyst to an inert solvent and controlling it at a moderate temperature, the two then react. After a rearrangement and construction of chemical bonds, an intermediate containing pyrrole ring is gradually formed. This intermediate is further modified to introduce methyl at the carboxyl group to obtain methyl-2,4,5-trimethyl-1H-pyrrole-3-carboxylic acid ester.
There are also other methods, starting with conjugated dienes and nitriles. Under the help of catalysts, the cyclization reaction occurs first to form the prototype of the pyrrole ring. Subsequently, the substituents on the ring are adjusted, and methyl groups are introduced in sequence through a series of reactions such as halogenation and alkylation, and finally ester is formed at the carboxyl group to obtain the target product. In this process, the choice of catalyst, the control of reaction temperature and time are all crucial, which are related to the success or failure of the reaction and the purity of the product. < Br >
Another method is to synthesize by multi-step tandem reaction. First, a simple hydrocarbon compound is used as the base, and a pyrrole ring is gradually constructed through several steps of reaction, and then methyl groups are introduced one by one, and the carboxyl group is converted to methyl ester group at a suitable stage. The advantage of this tandem reaction is that it can reduce the separation steps of intermediate products and improve the efficiency of synthesis. However, the requirements for the reaction conditions are more stringent, and each step needs to be carefully adjusted to achieve the best synthesis effect.
