Second, pyrrole derivatives are used as starting materials. Select an appropriate pyrrole compound, protect it with a specific group, and react with a reagent with a pyridine structure fragment in the presence of a catalyst to construct the mother nucleus of pyrrolido-pyridine. The choice of catalyst is crucial, or Lewis acid, etc. The subsequent steps are similar to the previous method, first reducing the double bond, and then forming a salt to obtain the target product.
Third, a multi-step cyclization strategy can be considered. Select an organic molecule containing multiple active check points, and through a gradual cyclization reaction, form a pyrrole ring first, and then construct a pyridine ring part. During this period, various cyclization reactions, such as intramolecular nucleophilic addition, dehydration and condensation, are skillfully used. After a series of reactions and post-treatment, the final target product is obtained.
In the process of synthesis, each method has its own advantages and disadvantages, and the choice needs to be weighed according to the availability of raw materials, the convenience of reaction conditions, and cost-effectiveness. In order to achieve the purpose of efficient synthesis.
