Definitions
- the present invention relates to a new process for resolving racemates.
- tetrahydropapaverine is split into its antipodes with the help of N-acetylleucine. This racemate resolution takes place according to a 3-step process:
- racemic 2-amino-1-butanol can be separated into its antipodes with (+) -2,4-dichlorophenoxypropionic acid.
- the invention relates to a process for the racemate separation of compounds of formula I.
- G H, C 1-4 alkyl, C 1-4 alkoxy, halogen, nitro or amino,
- T H, C 1 . 4 alkyl, C ⁇ - 4 alkoxy, halogen, nitro or cyano, or an optionally by C 1-4 alkyl, C. 1 4 alkoxy or halogen, mono-, di-, or trisubstituted phenyl ring, U: H, C 1-4 -alkyl, -4 alkoxy, halogen, nitro or cyano, V: H, C 1-4 alkyl, Cj . 4 -alkoxy or halogen.
- Suitable compounds of the formula I are preferably those in which the substituents have the following meanings:
- K is methoxy and L H, M H or methoxy,
- Q is methyl, R H, methyl or cyanomethylene.
- Deprenyl, ephedrine and in particular tetrahydropapaverine are particularly suitable as compounds of the formula I.
- Suitable compounds of the formula II are preferably those in which T is in the o-position and is H, fluorine, chlorine or methoxy, U is fluorine, chlorine or methoxy in the p-position and V is hydrogen.
- a particularly suitable compound of the formula II is (+) - or (-) -2- (2,4-dichlorophenoxy) propionic acid.
- the resolution can be carried out at temperatures between 0 ° C. and the boiling point of the solvent used. The easiest way is to work at room temperature.
- the cleavage can be carried out in customary solvents, such as lower alcohols, acetone, toluene, xylenes, ethers, tetrahydrofuran and ethyl acetate. Saturated solutions are usually used. Isopropanol or toluene is preferably used.
- the base can be released from the salt formed in the resolution of the racemate in aqueous solution at pH 7.5-10 and extracted with a water-insoluble solvent such as ether, toluene or a xylene.
- the new method is characterized by the fact that the cleavage reagents are easily available and stable. They also have a high selectivity and therefore provide the antipodes in good yields and in very high purity.
- the invention further relates to the salts of deprenyl, ephedrine and tetrahydropapaverine with a phenoxypropionic acid of the formula
- T is H, chlorine or methoxy and U is methoxy or chlorine.
- L-ephedrine-D-dichlorophenoxypropionate and especially the (+) -THP-D-24-dichlorophenoxypropionate should be mentioned.
- the product obtained was dissolved in 5 ml of water. After adjusting the pH of the solution to pH 8, extraction was carried out with toluene. After removal of the toluene, 0.48 g (93.3%) of the (+) enantiomer were obtained in an optical purity of 95.6%.
