What are the synthesis methods of 8-chloro-5,6-dihydro-11h-benzo [5,6] cyclohepta [1,2-b] pyridine-11-one
The synthesis method of 8-chloro-5,6-dihydro-11H-benzo [5,6] cycloheptano [1,2-b] pyridine-11-one has been known for a long time. In the past, many cycles were used to prepare this compound.
First, based on benzocycloheptanone derivatives, chlorine atoms were introduced through halogenation. This halogenation method, or using a chlorine source such as a chlorination reagent, in a suitable reaction environment, such as a specific solvent, temperature and catalyst, halogenates the specific check point of benzocycloheptanone, and then obtains a chlorine-containing intermediate. Then through the method of cyclization, the intermediate molecule is formed into a ring, and the structure of pyridinone is constructed, then 8-chloro-5,6-dihydro-11H-benzo [5,6] cycloheptano [1,2-b] pyridine-11-one is obtained.
Second, using pyridinone compounds as starting materials, the method of modifying the ring system is used. First, the surrounding ring system of pyridinone is constructed, and the structure of benzocycloheptyl is gradually built by suitable reactions, such as nucleophilic substitution, condensation, etc. The product can also be obtained when the ring system is initially formed, and then the halogenation step is carried out, and the chlorine atom is precisely introduced into the target position. When reacting, it is necessary to carefully observe the conditions of each step. The properties of the solvent, such as polarity and solubility, have a great influence on the process of the reaction and the purity of the product. Temperature control, or heating is required to promote the speed of the reaction, or low temperature is required to avoid the generation of side reactions. The choice of catalyst is also related to the efficiency of the reaction. Suitable catalysts can reduce the energy barrier of the reaction and increase the rate and selectivity of the reaction.
Third, there is also a strategy of multi-step series reaction. The starting material is reacted continuously in several steps without the need to separate the intermediate product, and it is completed in one go. This strategy requires a good understanding of the reaction mechanism, carefully designing the reaction sequence and conditions, so that each step of the reaction fits each other, so as to achieve the efficient synthesis of 8-chloro-5,6-dihydro-11H-benzo [5,6] cycloheptano [1,2-b] pyridine-11-one. However, although this multi-step tandem reaction is efficient, it requires very high control of the reaction conditions, and it is easy to cause the reaction to fail if there is a slight poor pool.
