There are various ways to prepare 1H-pyrrole-3-carboxylic acid. First, pyrrole can be used as a starting material. First, under specific conditions, pyrrole is acylated with a suitable acylating agent such as an acyl halide or an acid anhydride in the presence of a catalyst, and an acyl group is introduced at the 3-position of the pyrrole ring. Subsequently, the obtained acylation product, with a suitable oxidizing agent such as potassium permanganate or potassium dichromate, is oxidized in a suitable reaction medium to convert the acyl group into a carboxyl group to obtain 1H-pyrrole-3-carboxylic acid.
Second, furan derivatives containing suitable substituents can also be used as starting materials. The furan derivative and ammonia or amine compounds undergo aminolysis or aminolysis reaction under specific temperature, pressure and catalyst action, and are converted into pyrrole derivatives by rearrangement. After that, by selective oxidation of the substituents on the pyrrole derivatives, the carboxyl group is constructed at the 3 position to achieve the preparation of 1H-pyrrole-3-carboxylic acid.
Furthermore, the method of using halogenated pyrrole as raw material can be used. Select the halogenated pyrrole with a halogen atom located at the 3 position of pyrrole, react with carbon monoxide, a suitable base and a catalyst, and carry out carbonylation in a specific solvent at a certain temperature and pressure, so that the halogen atom is replaced by a carboxyl group, and the final 1H-pyrrole-3-carboxylic acid is obtained. These several preparation methods have their own advantages and disadvantages. In practical application, the appropriate method needs to be carefully selected according to the availability of raw materials, reaction conditions and costs.
