The chemical synthesis of 6-fluoro-1,2,3,4-tetrahydroisoquinoline has attracted much attention in the field of organic synthesis. Its synthesis methods are diverse, and are described in detail below.
The method is to use suitable aromatic compounds as starting materials. If fluorinated benzene derivatives are selected and reacted with vinyl halides or allyl halides with appropriate substituents under the catalysis of Lewis acid, a key carbon-carbon bond can be formed to preliminarily construct fluorinated phenylvinyl intermediates. Subsequently, the intermediate is hydrogenated under suitable hydrogenation conditions, such as in a metal catalyst (such as palladium carbon) and a hydrogen atmosphere, and the double bond is reduced to form a partially hydrogenated structure. Then, through the nucleophilic substitution reaction in the molecule, under the action of an appropriate base, the inner molecule is cyclized to form the basic skeleton of isoquinoline, and finally 6-fluoro-1,2,3,4-tetrahydroisoquinoline is obtained.
Another method can start from nitrogen-containing compounds. The Michael addition reaction is carried out with fluorine-containing anilines and compounds with α, β-unsaturated carbonyl groups to form an addition product. After that, the product undergoes an intra-molecular ring reaction under acidic or basic conditions to construct the isoquinoline ring system. Then through the controlled reduction step, the unsaturated bond is selectively reduced to obtain the target product.
Or the coupling reaction strategy catalyzed by transition metals. Under the action of transition metal (such as copper, palladium, etc.) catalysts and ligands, fluorinated halogenated aromatics and nitrogen-containing nucleophiles are coupled to form fluorine-containing nitrogen-aryl intermediates. Subsequently, through a series of functional group transformation and cyclization reactions, 6-fluoro-1,2,3,4-tetrahydroisoquinoline is synthesized.

6-Fluoro-1,2,3,4-tetrahydroisoquinoline is in the market, and its price range is not easy to determine. The price of this substance often changes due to various reasons.
First, its purity has a great impact on the price. If the purity is high, it can be applied to high-end scientific research, pharmaceutical preparation, etc., and the price will be high; if the purity is slightly lower, it can only be used for ordinary chemical purposes, and the price is relatively low.
Second, the supply and demand relationship in the market is also the key. If there are many people seeking, but there are few producers, the supply is in short supply, and the price will rise; conversely, if the supply exceeds the demand, the producers will compete to sell, and the price will decline.
Third, the difficulty of preparation also affects its price. If the preparation requires complicated processes and rare raw materials, the cost will be high, and the price will follow; if the preparation method is simple and the raw materials are easy to obtain, the price may be more affordable.
According to today's market conditions, the price of 6-fluoro-1,2,3,4-tetrahydroisoquinoline per gram is low or tens of yuan. If the purity is extremely high, it is suitable for those at the forefront of pharmaceutical research and development. The price per gram can reach hundreds of yuan, or even higher. However, this is only an approximate number. Market conditions are constantly changing, and the actual price needs to be carefully examined in the current market conditions, supply and demand trends, and the prices offered by various suppliers.
