Definitions
- the present invention relates to a process for the preparation of chiral amino acids with excellent enantiomeric excesses.
- chiral amino acids are among the most important. They are therefore prime targets for the pharmaceutical industry, with a potential that is all the greater as the enantiomeric excesses are close to 100%. To be efficient, the synthesis must take place with the best possible control of the chiral center.
- the other cases all describe an addition reaction of an organoboron compound to an ⁇ -aminoacrylate followed by an enantio-selective protonation.
- the reaction is catalyzed by a rhodium / bisphosphorus ligand combination.
- the organoboron compound is always selected from potassium aryltrifluoroborates or arylboronic acids. However, it is the pH of the medium that varies as well as the nature of the proton donor. Each time, it is necessary to heat at least up to 100 ° C and the enantiomeric excess is insufficient for one application industrial:
- Van der Eycken and collaborators (No ⁇ l T., Gôk Y, Van der Eycken, J.Tetrahedron Asymmetry 2010, 21, 540) use the same conditions as Reetz and Frost with the exception of the ligand and do not obtain better results. .
- the object of the invention is to provide a process for the preparation of chiral ⁇ -amino and ⁇ -amino acids with enantiomeric excesses greater than 95%.
- the object of the invention is to obtain good chemical yields in the preparation of these chiral amino acids.
- the object of the invention is to achieve synthesis under mild temperature conditions.
- the subject of the invention is the use of a solvent and a proton-donating element, whose pKa in water is greater than 7, in the presence of a base belonging to an acid pair.
- This reaction is catalyzed by a transition metal-containing complex and a bisphosphorus ligand. Chirality is carried by the ligand.
- the solvent makes it possible to dissolve all the species involved.
- a proton donor element also comes into play.
- the products obtained are chiral ⁇ - or ⁇ -amino acids, obtained in the form of species in which the amine and carboxylic acid functions. are protected.
- the reaction medium is not heated or is heated to a fairly gentle temperature.
- proton donor element refers to an acidic entity as defined by Bronst ⁇ d.
- the proton donor element is therefore a chemical species capable of yielding a proton to another species in the reaction medium.
- solvent refers to a liquid capable of solubilizing one or more chemical species and capable of maintaining the temperature of the reaction medium homogeneous at any point during the chemical transformation.
- chiral compounds consisting of ⁇ - or ⁇ -amino acids or their derivatives denotes ⁇ - or ⁇ -amino acids which may or may not be substituted by one or more elements or groups, which may be identical or different, said ⁇ - or ⁇ -acids. substituted or unsubstituted amines being chiral, said groups not being themselves constituted of ⁇ - or ⁇ -amino acids.
- enantiomeric excess refers to the physical quantity quantifying the optical purity of a compound obtained during a chemical reaction.
- ⁇ -aminoacrylates includes ⁇ -amino acids and ⁇ -amino acids
- R, R, P, P have the meanings given below. When n is 0, it is an ⁇ -amino ester and when n is 1, it is a ⁇ -amino ester.
- organoboron compound refers to a chemical compound having a boron-carbon bond. Several families of organoboron compounds are used.
- organoboron compounds used in the present invention are either commercial compounds or compounds accessible by synthesis. They are stable and easily handled compounds.
- ligand refers to a molecule carrying chemical functions that allows it to bind to a metal atom or a central metal cation.
- bisphosphorus ligand refers to a ligand having two phosphorus atoms. These ligands belong to the diphosphine family. Each phosphorus atom is therefore trivalent and has a non-binder electronic doublet that can be transferred to the metal of transition.
- the ligands used in the invention are chiral diphosphines by atropoisomerism; they therefore present an axial chirality.
- the enantiomer is related to the prevention of rotation around a single bond.
- the steric hindrance of the substituents around this bond is such that at ordinary temperature the rate of interconversion is sufficiently low for the two enantiomers to be separated.
- these diphosphines can be easily complexed to a large number of transition metals for many enantioselective catalytic reactions.
- the atropoisomeric systems thus prove to be of great importance in asymmetric synthesis.
- the bisphosphorus ligand is therefore a bidentate ligand (dentition equal to two).
- the bisphosphorus ligand forms, in combination with a metal atom or a metal cation, a coordination complex.
- electron-poor biphosphoric ligand refers to a ligand which is a diphosphine whose substituent carries electron-withdrawing groups.
- the scale defined by the phosphorus / selenium coupling constant denoted Jp_s e (DW Allen, Taylor BF, J. Chem Soc, Dalton Trans, 1982, 51-54) is used. .
- the ligand is selected such that J P _ Se> 720 Hz.
- the term "catalyst” refers to a complex containing a transition metal.This complex is capable of increasing the reaction rate.The transition metal is selected from groups 8, 9 and 10 of the periodic table.
- the first key step corresponds to the addition-1, 4 of the organoboron compound on ⁇ - aminoacrylate.
- the carbon group attached to the boron atom is transferred to the ⁇ -aminoacrylate.
- a new carbon-carbon bond is thus formed between this group, provided by the organoboron compound, and ⁇ -aminoacrylate.
- a reaction intermediate is obtained, probably of the oxa-7-allylmetal type. This complex is chiral since the metal / chiral ligand association is one of them.
- the proton donor element transfers its proton to the previously formed chiral reaction intermediate.
- This protonation is diastereo selective: it controls the chiral center.
- the proton donor is the solvent and is especially chosen from primary, secondary or tertiary alcohols containing from 1 to 8 carbon atoms and especially chosen from methanol, ethanol, n-propanol, n-butanol, isopropanol, sec-butanol, isobutanol and tert-butanol.
- the proton donor element defined above is the solvent itself. It is selected from the three classes of alcohols.
- alcohols are good solvents. In the invention, they make it possible to dissolve all or part of the compounds involved in the procedure.
- alcohol primary, secondary, tertiary, and especially secondary alcohols.
- the alcohol belongs to the class of primary alcohols, it has 1 to 8 carbon atoms and is especially selected from methanol, ethanol, n-propanol and n-butanol.
- the reaction products are then generally obtained with enantiomeric excesses greater than
- the alcohol belongs to the class of secondary alcohols, it has from 3 to 8 carbon atoms and is chosen from isopropanol or sec-butanol, and in particular isopropanol.
- the reaction products are then advantageously obtained with enantiomeric excesses of the order of 99%, this indication not being limiting.
