The chemical synthesis method of 1-phenyl-3,4-dihydroisoquinoline has been known in ancient times and is now the number of Jun Chen.
First, it can be started from phenethylamine and benzaldehyde. Under the catalysis of acid, phenethylamine and benzaldehyde are condensed to obtain Schiff base. Then, the Schiff base is treated with a reducing agent such as sodium borohydride to reduce 1-phenyl-3,4-dihydroisoquinoline. This is a classic method, the operation is relatively simple, and the raw materials are easy to obtain.
There are also those who use o-halobenzyl halide and phenethylamine as raw materials. Under basic conditions, the nucleophilic substitution reaction of o-halobenzyl halide and phenethylamine occurs to form a ring to obtain the target product. This process requires attention to the regulation of the strength of the base and the reaction temperature to ensure the smooth progress of the reaction, and the purity of the product can also be guaranteed.
Furthermore, the reaction catalyzed by transition metals. For example, the cyclization reaction catalyzed by palladium, with suitable halogenated aromatics and alkenylamines as substrates, under the combined action of palladium catalyst, ligand and base, the cyclization reaction generates 1-phenyl-3,4-dihydroisoquinoline. This method has the characteristics of high efficiency and good selectivity, but the catalyst cost is higher and the reaction conditions are more demanding.
Another person has constructed this structure by Fu-gram reaction. With phenethylamine derivatives and benzoyl chloride and other acylating reagents, under the catalysis of Lewis acid, the Fu-gram acylation reaction is first carried out, and then converted into 1-phenyl-3,4-dihydroisoquinoline through reduction and other steps. This approach requires attention to the selectivity of acylation sites and the optimization of subsequent reduction steps.
All methods have advantages and disadvantages. In actual synthesis, factors such as the availability of raw materials, the ease of control of reaction conditions, the purity and yield of the product should be weighed and selected.
