2%2C3+-+dihydro+-+1H+-+benzo%5Bde%5Disoquinoline is 2,3-dihydro-1H-benzo [de] isoquinoline, and its synthesis method is as follows:
It can be prepared by the multi-step reaction of phthalic anhydride and β-phenethylamine. First, phthalic anhydride and β-phenethylamine are condensed under appropriate conditions to form an intermediate product. This process requires temperature control and time control to promote the full reaction of the two to obtain amide intermediates.
Then, the reduction operation of this intermediate is carried out. Strong reducing agents such as lithium aluminum hydride are commonly used to react in an anhydrous and inert gas-protected environment to reduce the amide group to methylene, and the key intermediate is obtained. The reaction conditions in this step are severe, and it is necessary to avoid water and oxygen to prevent the failure of lithium aluminum hydride and side reactions.
Then, the key intermediate is cyclized. Under the catalysis of suitable acids, such as concentrated sulfuric acid or Lewis acid, the ring is closed in the molecule to form the parent nuclear structure of 2,3-dihydro-1H-benzo [de] isoquinoline. After the reaction is completed, the pure target product can be obtained by separation and purification methods such as neutralization, extraction, column chromatography, etc.
Another method is to use phenanthridine compounds as the starting material. Phenanthrene is selectively reduced by specific reducing reagents, such as sodium borohydride, in a suitable solvent to form 2,3-dihydro-1H-benzo [de] isoquinoline. This path is relatively simple, but the cost of starting raw material phenanthrene may be relatively high, and the cost and benefit need to be weighed. Each method has advantages and disadvantages. In actual synthesis, the best synthesis route should be selected according to factors such as raw material availability, cost, yield and purity requirements.
