Description
The present invention relates to a process for producing racemic or optically active α-glycerophosphoryl choline, wherein the high purity of the racemic or optically active D or L-α- in a simple manufacturing process and low cost Glycerphosphoryl choline is to be produced in large quantities.
Racemic or optically active D or L-α-glycerophosphoryl choline is a compound represented by the following formula (1), which is a secondary symptom due to cerebrovascular defects and senile perception such as degenerative or degenerative brain matrix mental syndrome It is known to have excellent effects in treating elderly caustic depression, such as disorders (low memory, confusion, disorientation, decreased motivation and spontaneity, decreased concentration), emotional and behavioral changes (emotional anxiety, irritability, lack of interest), By promoting the production of acetylcholine, a neurotransmitter in the brain, it is known as an excellent drug that normalizes the abnormality of the choline nerve transmission system due to the lack of acetylcholine and normalizes the function of damaged neurons.
[Formula 1]
Where * is a chiral center and refers to racemic and optically active D or L-α-optical isomers.
As such, racemic or optically active D or L-α-glycerophosphoryl choline with good pharmacological effects may be prepared by organic synthesis, It can also be prepared by deacylating acyl phospholipid, and the typical method is as follows.
First, Korean Patent No. 0262281 discloses a method of deacylating a phospholipid mixture obtained by natural or synthetic reaction by alcohol decomposition as in Scheme 1 below, and preparing glycerophosphoryl choline using a basic ion exchange resin. This is known. However, this method is a method of purifying phospholipids containing excessive impurities in the starting material by deacylation reaction to produce glycerophosphoryl choline, and the recovery rate of glycerophosphoryl choline is low. Since the basic ion exchange resin is used, there is a disadvantage that it is not suitable for mass production.
Scheme 1
Wherein R and R1 may be the same or different and are C13-C25 alkyl, C13-C25 mono or poly unsubstituted alkenyl.
U.S. Pat.No. 5,525,1919 discloses a process for preparing L-α-glycerophosphoryl choline by a method similar to Scheme 1, but this method also requires a purification process using an ion exchange resin. , L-α-glycerophosphoryl choline has the disadvantage of low recovery.
In addition, a method of preparing glycerophosphoryl choline through deacylation of lecithin extracted from plant material or animal organ is known (Biochim. Biophys . Acta , 488: 36, 1977; Biochim. Biophys. Acta, 1003: 277, 1989), depending on the reaction conditions (reaction time, temperature, base and solvent type) of the deacylation reaction, various by-products such as D-1,2-glycerophosphate are produced and purified. The disadvantages are complex and low yields.
As shown in the above known examples, in the preparation of L-α-glycerophosphoryl choline, methods using a substance such as lecithin extracted from a plant or animal may be used to prepare L-α-glycerophosphoryl choline. Although there is an advantage in that the necessary materials can be easily obtained in nature, since an excessive amount of impurities are included in the extraction process, it needs to be purified using ion exchange resin, etc., so that the purification process is complicated, difficult to manufacture with high purity, and low recovery rate. Not only is it uneconomical, but also unsuitable for industrial mass production.
On the other hand, looking at the conventional method for preparing glycerophosphoryl choline by the organic synthesis method, D, L-α-glycerophosphoryl choline using D, L-acetone glycerol as a starting material as shown in Scheme 2 below ( J. Org . Chem. , 26: 608, 1961), but since the reaction proceeds in a total of four steps, the reaction process is complicated and the reaction is carried out under anhydrous conditions. The disadvantage is that the process is difficult. In particular, the starting materials D and L-acetone glycerol are very expensive, and expensive compounds such as palladium and silver carbonate are used to remove phenyl groups and chlorine ions that act as protecting groups of the reaction, making them difficult to apply industrially. There are disadvantages.
Scheme 2
EP 468100 discloses a racemic or L-α-glycerophosphate from the substitution reaction of isopropylidene glycerol and 2-chloro-2-oxa-3,3,2-dioxophospholane, as shown in Scheme 3 below. A method of preparing foryl choline is disclosed. However, this method also uses expensive isopropylidene glycerol and 2-chloro-2-oxa-3,3,2-dioxophosphola as starting materials. There is a problem in that after the hydrolysis reaction, the racemic or L-α-glycerophosphoryl choline must be purified using an ion exchange resin.
Scheme 3
Here, * is chiral center and means racemic or L-form optical isomer.
In addition, Korean Patent Application Publication No. 2007-0119176 discloses calcium 2- (trimethylammonio) ethylphosphate chloride tetrahydrate by removing calcium ions under acid conditions to obtain cholinephosphate chloride, as shown in Scheme 4. L-α-glycerophosphoryl choline chloride was prepared by performing a ring opening reaction with (R) -glycidol on the chlorine, and then using the ion exchange resin, A method of removing ions and producing L-α-glycerophosphoryl choline is disclosed.
Scheme 4
However, this method is not only expensive in terms of (R) -glycidol, which is used as a key intermediate of the reaction, but also yields a high reaction yield because (R) -glycidol is unstable and easily decomposed during the ring opening reaction. Low and in particular, there is a disadvantage in that it is difficult to produce L-α-glycerophosphoryl choline with high purity because the method for purifying glycerol produced in large quantities as a byproduct is difficult. In addition, since the reaction proceeds in several stages, the manufacturing process is complicated and uneconomical. In the final stage, L-α-glycerophosphoryl choline is purified in a large amount by using an ion exchange resin to remove chlorine ions. There are many problems in manufacturing.
Accordingly, the present inventors have intensively tried to improve the problems of the prior art, and as a result, the racemic or optically active (S) or (R) -epihalohydrin derivatives and cholinephosphate or salts thereof are ringed in the presence of a medium. By carrying out the one-pot reaction through the opening reaction, it is possible to economically and easily prepare racemic or optically active D or L-α-glycerophosphoryl choline with high purity and high yield without a separate purification process. It was confirmed that this can be done, and the present invention has been completed.
It is an object of the present invention to provide a method for producing large amounts of racemic or optically active D or L-α-glycerophosphoryl choline with high optical purity at a simple manufacturing process and at low cost.
