At the beginning, a compound containing indolicidine structure can be selected as the starting material. This raw material has been carefully designed and processed to lay the foundation for subsequent reactions. The first step is to make the starting material and a specific halogenated alkane hydrocarbon in a suitable solvent, catalyzed by a base, and perform nucleophilic substitution reaction. The selection of halogenated alkanes needs to meet the structural requirements of the target product, and ethyl groups such as ethyl groups are precisely introduced. The control of this reaction condition is crucial. The polarity of the solvent, the strength and dosage of the base will all affect the process and yield of the reaction.

Then, for the introduced group, hydroxylation is performed. This step can be achieved by oxidation. For example, a suitable oxidizing agent is selected to convert the specific carbon-hydrogen bond into a hydroxyl group under mild reaction conditions. There are many kinds of oxidizing agents, which should be carefully selected according to the characteristics of the substrate and the selectivity of the reaction. And during the reaction process, care should be taken to avoid excessive oxidation, so as not to damage other structures of the molecule.

As for the key part of introducing 11- [2- (isopropylamino) ethyl], it can be gradually constructed through a multi-step reaction. First, the specific position of the molecule is activated with a suitable reagent, and then it is reacted with a reagent containing isopropylamino ethyl structure. In this process, various reaction mechanisms such as nucleophilic addition and condensation are involved. The optimization of reaction sequence and conditions is related to the purity and yield of the final product.

When constructing the structure of pyrano and quinolinedione, intracolecular cyclization reactions are required. By adjusting the pH, temperature and other conditions of the reaction system, the molecules are cyclized to form a specific cyclic structure of the target product. This cyclization reaction is the core step of synthesis, and precise control of various parameters is required to ensure the smooth progress of cyclization and obtain the ideal product.

After each step of the reaction, it is necessary to use separation and purification methods such as column chromatography and recrystallization to remove impurities and improve the purity of the product.

Polycyclic structure endows it with rigidity, or is essential for the selectivity and affinity of receptor binding.

Although it has not been seen for specific drug applications, it may be used to develop drugs for neurological diseases according to modern medicinal chemistry theory, because polycyclic indole structures often have neuroactivity. Or for the development of anticancer drugs, some compounds containing quinolinodione structures have shown anti-cancer potential. This compound may inhibit the proliferation of cancer cells due to its unique structure binding to active check points.

In summary, although the exact drug use has not been heard today, its structural characteristics suggest that it has potential value in many fields of drug development, which will be further explored by future doctors and medicine practitioners.
