To prepare 4-alkane-1,2-dihydroxynaphthalene, the ancient method followed the principle of organic synthesis. First, the derivative of naphthalene can be used as a starting point, and the alkyl group can be introduced into the 4 position of the naphthalene ring by electrophilic substitution. Usually halogenated alkyl and naphthalene are catalyzed by Lewis acid such as aluminum trichloride to perform Fu-gram alkylation reaction. After obtaining 4-alkane naphthalene, the dihydroxyl group is added to the 1,2 position by oxidation. A mild oxidizing agent, such as peroxy acid, can be selected to form an epoxy intermediate first, and then hydrolyzed to obtain a 1,2-dihydroxyl structure.
Second, the alkyl group can also be introduced at the 4-position with 1,2-dihydroxy naphthalene as the group. The phenolic hydroxyl group of 1,2-dihydroxy naphthalene has a certain activity and can be protected first to prevent it from interfering in the reaction. Commonly used protective groups such as silicon ethers. After protection, the target alkyl group is introduced by the method of Fu-gram alkylation. After alkylation is completed, the protective group is removed to give 4-alkane-1,2-dihydroxy naphthalene.
Or natural products can be found as starting materials. If there are those containing similar structures, they can be obtained by modification and transformation in several steps. This method requires detailed investigation of the structure and reactivity of the natural product, and precise introduction of the required groups by enzymatic reaction or chemical modification. However, the source of the natural product may be limited, and the separation and purification steps are complicated.
In addition, the idea of molecular design and reverse synthesis analysis is also considered. The structure of the target product is analyzed first, and possible intermediates and starting materials can be obtained by inverse inference. According to this, the synthesis path is planned, the feasibility, yield and selectivity of each step of the reaction are considered, and the synthesis method is optimized, and 4-alkane-1,2-dihydroxynaphthalene is obtained efficiently.

4-Hydrocarbon-1,2-dicarboxylbenzene, this substance has various effects on the environment and human body.
In terms of the environment, if it is released in nature, some of it can gradually disappear through photolysis, microbial degradation and other pathways. However, the degradation rate varies depending on environmental conditions. The degradation rate varies in oxygen-enriched and microbial environments, but is slow in anaerobic or extreme environments. And because of its special structure, if it accumulates in large quantities, it may affect soil and water ecology. In soil, or change soil quality, affect plant root absorption of nutrients, causing plant growth to be hindered; in water, or interfere with the normal physiology of aquatic organisms, such as affecting algae photosynthesis, and then disrupt the balance of aquatic ecological chains.
As for the human body, 4-hydrocarbon-1,2-dicarboxylbenzene may be introduced into the body through respiratory, dietary, and skin contact. After entry, it may interact with biological macromolecules such as proteins and nucleic acids. Studies have shown that it may have potential genotoxicity, interfere with the normal expression and replication of genes, and in the long run, increase gene mutations and even the risk of cancer. And may irritate the skin and mucous membranes, causing skin allergies, redness and swelling, respiratory discomfort, such as cough, asthma, etc. At the same time, it may accumulate in the body and damage the functions of important organs such as the liver and kidneys. Because of its metabolism, long-term exposure makes the organs overloaded, affecting normal metabolism and detoxification, and then damaging physical health.
Therefore, for 4-hydrocarbon-1,2-dicarboxylbenzene, it should be handled with caution, and the production and use should be strictly controlled to reduce its harm to the environment and the human body.
