The method of synthesizing isoquino [4 ', 5', 6 ': 6,5,10] anthra [2,1,9 - def] isoquinoline - 1,3,8,10 (2H, 9H) -tetrone has various paths. One method is to first take an appropriate aromatic compound as the starting material, such as one containing a benzene ring with a specific substituent. After halogenation, a halogen atom is introduced into the benzene ring. This halogen atom can be bromine or chlorine. When halogenating, attention must be paid to the reaction conditions, such as temperature and catalyst selection. Commonly used catalysts include iron or iron salts, and the temperature varies depending on the raw material used and the halogenating agent, which is generally controlled between tens of degrees Celsius.
Then, the halogenated product is coupled to a compound with an nitrogen heterocyclic structure. The key to the coupling reaction is to choose the appropriate catalyst and ligand. Common catalysts such as palladium catalysts have a wide variety of ligands, which can be selected according to the needs of the reaction. This step aims to construct the basic skeleton of isoquino [4 ', 5', 6 ': 6,5,10] anthra [2,1,9 - def] isoquinoline.
Furthermore, the obtained skeleton compound is oxidized. The purpose of oxidation is to convert carbon atoms at specific positions into carbonyl groups to achieve the structure of 1, 3, 8, 10 (2H, 9H) -tetrone. Appropriate oxidizing agents can be selected for the oxidation reaction, such as chromium anhydride, etc. The reaction conditions also need to be carefully adjusted, such as reaction time, temperature and ratio of reactants. If the temperature is too high or the reaction time is too long, it may cause excessive oxidation and damage the purity and yield of the target product.
There are other methods, or the fragment containing nitrogen heterocycles can be constructed first, and then connected to the related fragment containing anthracycline through condensation and other reactions. The condensation reaction also requires careful selection of reaction reagents and conditions to promote the effective binding of the two fragments and minimize the occurrence of side reactions.
All synthesis methods require fine control of the reaction conditions at each step, and attention to the separation and purification of intermediates to obtain the target product isoquino [4 ', 5', 6 ': 6,5,10] anthra [2,1,9 - def] isoquinoline - 1,3,8,10 (2H, 9H) -tetrone.

This compound is called isoquinolino [4 ', 5', 6 ': 6,5,10] anthracene [2,1,9-def] isoquinoline-1,3,8,10 (2H, 9H) -tetraketone. Its stability involves many chemical factors and can be analyzed from the following aspects.
Structurally, this compound contains multiple fused aromatic ring structures. Aromatic rings have special stability due to the existence of conjugated systems. The fusing of multiple aromatic rings further extends the conjugated system and increases the degree of electron delocalization. According to Huecker's rule, this usually enhances molecular stability. For example, fused aromatic hydrocarbons such as naphthalene and anthracene are relatively stable due to conjugation. This compound is similar to it, and the fused aromatic ring structure is its stable basis.
The chemical bonds within the molecule have a significant impact on the stability. The bond energy of covalent bonds such as C-C bonds and C-N bonds determines the stability of the molecule. These bonds have higher energy and require more energy to break, giving the molecule a certain stability. At the same time, there may be weak interactions such as hydrogen bonds in the molecule. If hydrogen bonds are formed in the molecule, the rigidity of the molecular structure can be enhanced and the stability can be improved. For example, in many organic compounds, hydrogen bonds can form a stable conformation of the molecule.
External environmental factors cannot be ignored. When the temperature increases, the thermal motion of the molecule intensifies, which may weaken the intramolecular interaction and reduce the stability; in the environment of strong acids, strong bases or strong redox, the compound may react and the stability will be affected. For example, strong oxidants may oxidize some groups in the molecule and change the structure.
Overall, this compound has certain stability due to the large conjugated system formed by fused aromatic rings and higher bond energy chemical bonds, but external environmental changes may change its stability state.
