Abstract
The invention relates to the technical field of drug synthesis, in particular to a preparation method of flurbiprofen, which comprises the following steps: 4-bromo-2-fluorobiphenyl and trimethylsilyl acetylene are subjected to Sonogashira coupling reaction under the catalysis of palladium to obtain 4-trimethylsilyl ethynyl-2-fluorobiphenyl, and the product is subjected to removal of trimethylsilyl in an alkaline solution without separation to obtain 4-ethynyl-2-fluorobiphenyl; and then taking a complex formed in situ by nickel and phosphine ligands as a catalyst, taking formic acid as a carboxylation and hydrogenation reagent, carrying out hydrocarboxylation-hydrogenation tandem reaction on the 4-ethynyl-2-fluorobiphenyl, and purifying to obtain the flurbiprofen. The raw material source is easy to obtain, the route is short, the operation is simple and convenient, the reaction condition is mild, and the yield is high; the ethynyl is directly converted into the propionic acid group through an efficient one-pot tandem reaction, and the racemic flurbiprofen, the levorotatory flurbiprofen and the dextrorotatory flurbiprofen can be synthesized only by changing the types of phosphine ligands, so that the racemic flurbiprofen is prevented from being prepared into the optically pure flurbiprofen through fussy and inefficient resolution.
Description
The invention is a divisional application, and the original application number is as follows: 202110104844.0, filing date: to 2021.01.26, the invention creates the name: a method for preparing flurbiprofen.
Technical Field
The invention relates to the technical field of drug synthesis, in particular to a preparation method of flurbiprofen, which is used for preparing racemic flurbiprofen, optically pure levorotatory flurbiprofen and dextrorotatory flurbiprofen.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
The chemical name of Flurbiprofen (Flurbiprofen) is 2- (2-fluoro-4-biphenyl) -propionic acid, and the chemical structure is shown as (1). Is a powerful non-steroidal anti-inflammatory analgesic developed by British Blakez company. The anti-inflammatory and analgesic effects of the aspirin sustained-release tablet are respectively 250 times and 50 times of those of aspirin, the aspirin sustained-release tablet is stronger than ibuprofen, and the ibuprofen sustained-release tablet is lower in toxicity and is the most powerful one of the currently known propionic acid non-steroidal anti-inflammatory drugs. It is used for treating rheumatic arthritis, rheumatoid arthritis, ankylosing spondylitis, degenerative arthritis, eye inflammation, etc., and can also be used for relieving traumatic pain, postoperative pain and various cancer pain. From the chemical structure, flurbiprofen contains one chiral carbon atom, and thus has a pair of enantiomers (2) and (3). Although the racemes are used in the prior medicine, the research shows that the two isomers have different physiological activities, the anti-inflammatory and analgesic activities of the flurbiprofen are mainly generated by the dextroisomer (S) - (+) -flurbiprofen (2), and the levoisomer (R) - (-) -flurbiprofen (3) has anticancer activity and can be also used for treating senile dementia. Therefore, the synthesis of optically pure levorotatory flurbiprofen and dextrorotatory flurbiprofen is of great significance, and can reduce the dosage, reduce side effects, treat different types of diseases and the like.
At present, various methods for synthesizing racemic flurbiprofen have been reported at home and abroad, wherein the various methods have the problems of long reaction route, difficult raw material source, complex operation, harsh conditions and the like. There are also many routes which involve the intermediate of 4-bromo-2-fluorobiphenyl or directly as starting material, where 4-bromo-2-fluorobiphenyl is prepared as grignard reagent, coupled with 2-halopropionate, sodium 2-halopropionate or 2-cyanopropionate, and hydrolyzed or acidified to obtain flurbiprofen. Although the reaction is simple, strict anhydrous conditions are required for preparing the grignard reagent, and the reaction needs to be monitored closely to prevent safety problems such as material flushing and deflagration caused by sudden heat release. The research shows that 4-bromo-2-fluorobiphenyl is converted into 4-vinyl-2-fluorobiphenyl through Grignard reaction, alpha-carboxylation is carried out under palladium catalysis and 30Bar carbon monoxide pressure to obtain flurbiprofen, noble metal and high-pressure CO are needed in the route, and the product contains beta-carboxylation products, so that the separation is difficult and the method is not suitable for large-scale production. In other researches, 4-bromo-2-fluorobiphenyl is converted into corresponding boric acid, the boric acid is coupled with 2-diazopropionate to obtain acrylic ester, and flurbiprofen is obtained through hydrogenation and hydrolysis.
The optically pure flurbiprofen is mainly obtained by resolution or asymmetric synthesis of racemate. Chemical resolving agents reported are, for example, dextran octylamine, isosorbide monobenzyl ether, (S) -phenylethylamine, (S) -3-methyl-2-phenylbutylamine, chiral beta-hydroxyamino acids, etc., which give only levo-or dextro-flurbiprofen of high optical purity, reported yields being calculated on the basis of half of the racemic material (the content of the isomer), generally between 60 and 80%, while the optical purity of the other isomer is not high or is discarded. The racemic flurbiprofen and the chiral resolution reagent are precious, and the chemical resolution method has complicated repeated recrystallization steps, so the production cost is high. Through the method of catalyzing biphenylmalonate decarboxylation or biphenylpropionic acid ethyl ester hydrolysis, although levorotatory flurbiprofen and dextrorotatory flurbiprofen can be obtained at the same time, the cost is very high, the steps are complicated, and the yield is low. The high performance liquid chromatography or the chiral ionic liquid resolution method also has the problems of expensive chiral column packing, limited resolution scale and the like. In the literature, chiral transition metal catalyst is used to perform asymmetric hydrogenation on biphenylyl acrylic acid to obtain dextro-flurbiprofen with high optical purity, wherein the biphenylyl acrylic acid can be obtained by converting 4-bromo-2-fluorobiphenyl into 4-acetylene-2-fluorobiphenyl through palladium-catalyzed coupling reaction and then performing palladium-catalyzed hydrocarboxylation reaction, or by coupling 4-bromo-2-fluorobiphenyl with pyruvate through Grignard reaction and then heating and dehydrating. The total synthesis route is still longer, the steps of separation and purification are more, and the noble metal catalyst is more used.
The inventors found that for the synthetic route of racemic and optically pure flurbiprofen, many pharmaceutical enterprises and colleges are continuously trying to develop more effective and concise synthetic routes due to the excellent anti-inflammatory analgesic and other potential efficacies of flurbiprofen; in the synthetic route in the prior art, only a racemate can be generally obtained, and then one of a left-handed rotation or a right-handed rotation is obtained through resolution; it still needs to design more reasonable starting materials, shortens the synthetic route and reduces the use of chiral noble metal catalysts.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a preparation method of flurbiprofen, which can synthesize racemic flurbiprofen, levo-flurbiprofen and dextro-flurbiprofen by selecting a suitable catalyst ligand from 4-bromo-2-fluorobiphenyl as a raw material, and has the advantages of short synthetic route, high yield, low consumption, health, safety, environmental protection and the like.
