Abstract
The application belongs to pharmaceutical synthesis field, is related to a kind of preparation method of chiral phosphorus acid esters.Specifically, the application is related to the method that compound shown in Formulas I R is converted into compound shown in Formulas I S.The preparation method of the application has the advantages of high income, product chiral purity is high, be adapted to industrialized production the advantages of.
Description
Technical field
The application belongs to pharmaceutical synthesis field, in particular to a kind of preparation method of chiral phosphorus acid esters.
Background technology
Lucky moral is developed after purchase method not Saite and has listed Suo Feibuwei (sofosbuvir, PSI-7977, GS-
7977,).2013, FDA approval Suo Feibuwei were combined with Ribavirin (RBV), for the type of HCV genes 2 and 3 types
The oral medication of patient；And ratify, with injecting spent glycol interferon (pegIFN) and Ribavirin (RBV) drug combination, to be used for
Treat the first patient of HCV genes 1 and 4 types.Suo Feibuwei treatment cycle is longer, it usually needs the course for the treatment of in 12 weeks -24 weeks, controls
Treatment expense is extremely expensive, and the whole world only has only a few patient and can bear the treatment and benefit at present.
Compound shown in Formulas I-S can be as the intermediate for preparing Suo Feibuwei, and it reacts to obtain rope with the compound of formula II
Fei Buwei：
In the preparation method of compound shown in existing Formulas I-S, products therefrom includes diastereoisomer impurity Formulas I-R institutes
Show compoundWO2011123645 discloses one kind and converts compound shown in Formulas I-R
For the method for compound shown in Formulas I-S, but this method is cumbersome, and products therefrom yield needs further to improve.Also, product
In compound, compound property shown in Formulas I-R shown in more residual Formulas I-R approached with compound shown in Formulas I-S, it is difficult to remove,
Influence the chiral purity of target product Suo Feibuwei obtained by subsequent reactions.
The content of the invention
On the one hand, the application offer is a kind of is converted into compound shown in Formulas I-S by compound shown in Formulas I-R in the solution
Method, including compound shown in Formulas I-R is converted into compound shown in Formulas I-S under the conditions of existing for nucleophilicity alkali, solvent：
The nucleophilicity alkali is selected from sodium methoxide, potassium tert-butoxide, sodium tert-butoxide, sodium acetate, potassium acetate, sodium propionate, potassium propionate
Or Pentafluorophenol sodium.
In some embodiments of the application, compound shown in Formulas I-R is converted into chemical combination shown in Formulas I-S in the solution
In the method for thing, the nucleophilicity alkali preferably is selected from sodium methoxide.
In some embodiments of the application, compound shown in Formulas I-R is converted into chemical combination shown in Formulas I-S in the solution
In the method for thing, the inventory of the nucleophilicity alkali is selected from 0.02~0.50 equivalent, preferably be selected from 0.02,0.05,0.08,0.10,
0.12nd, 0.15,0.18,0.20,0.22,0.25,0.28,0.30,0.32,0.35,0.38,0.40,0.42,0.45,0.48 or
0.50 equivalent.
In some embodiments of the application, compound shown in Formulas I-R is converted into chemical combination shown in Formulas I-S in the solution
In the method for thing, the solvent is selected from ethyl acetate, dichloromethane, acetone, acetonitrile, DMF, Isosorbide-5-Nitrae-dioxy
Six rings, tetrahydrofuran, 2- methyltetrahydrofurans, methyl tertiary butyl ether(MTBE), isopropyl ether, ether, glycol dimethyl ether, normal heptane, just
Hexane or any two or more mixed solvent, preferably are selected from ethyl acetate, methyl tertiary butyl ether(MTBE), isopropyl ether, ether, ethylene glycol two
Methyl ether, normal heptane, n-hexane, hexamethylene or any two or more mixed solvent, more preferably from methyl tertiary butyl ether(MTBE), isopropyl
Ether, the mixed solvent of ethyl acetate and n-hexane, mixed solvent, ethyl acetate and the isopropyl of ethyl acetate and methyl tertiary butyl ether(MTBE)
The mixed solvent of ether.
In some embodiments of the application, compound shown in Formulas I-R is converted into chemical combination shown in Formulas I-S in the solution
In the method for thing, the solvent load is selected from 1~10 times of volume, preferably be selected from 1 times, 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times,
9 times or 10 times of volumes.
