Definitions
- the invention relates to a process for the preparation of omega-amino acids or their esters by ozonolysis and subsequent reductive amination. Another object of the invention is a process for the preparation of
- ozonolysis is understood as meaning the cleavage of a carbon-carbon double bond by the action of ozone.
- carbonyl compounds, alcohols or carboxylic acids are obtained.
- the reaction proceeds by 1,3-dipolar cycloaddition of ozone to a C, C double bond of an olefin (1) to form the primary ozonide (1, 2,3-trioxolane, 2).
- the radical R is hydrogen, an alkyl group
- Alkylene group, alkynyl group or an aryl group may be the same or different in a molecule and are optionally
- This compound (2) is an unstable one
- the carbonyl oxide can on the one hand polymerize or dimerize to a 1, 2,4,5-tetraoxolane (5), or in a further cycloaddition to a Secondary zonide (1,2,4-trioxolane, 6) recombine.
- aldehydes (7, 8) can be prepared via a reductive or carboxylic acid (9, 10) via an oxidative work-up.
- the aldehydes in turn can be further reduced to the alcohol.
- the prior art has detected the trapping of the carbonyl oxide (4) with the aid of a nucleophile, e.g. an alcohol, described. In most cases, the nucleophile is also the solvent. Recombination with the carbonyl group of the second cleavage product (3) to the secondary ozonide is thus prevented (SL Schreiber et al., Tel Lett., 1982, 23 (38), 3867; RE Claus, SL Schreiber Organic Syntheses, Coli., Vol. 1990, 68).
- a nucleophile e.g. an alcohol
- the hydroperoxide group (11) is acetylated and decomposed under basic catalysis, with a
- Carboxyl group of the carboxylic acid added to the carbonyl oxide 4.
- the workup of the hydroperoxide derivative (14) is again as described.
- the mixed anhydride (15) formed in the basic cleavage still has to be cleaved with water to give the free acid (16).
- the primary acid zonide 18 can be split at position 5 (path a) or at position 4 (path b) of the 1,2,3-trioxolane.
- the respective carbonyl oxide intermediate is trapped by the acetic acid.
- the hydroperoxide group of compounds 20 and 24 is acetylated with acetic anhydride. Since there is now a comparatively good leaving group (acetate group) and an acidic proton, a deprotonation takes place with the addition of sodium acetate as base, with elimination of the acetate group, from which compounds 21 and 25 initially form the anhydrides of 22 and 26. After cleavage of these anhydrides with water, the entprechende monocarboxylic acid or dicarboxylic acid monomethyl ester are obtained.
- NMMO N-methylmorpholine-N-oxide
- DE 34 40 620 A1 describes the effect of water in the ozonolysis of fatty acid derivatives. It has been observed that in the presence of water in the reaction mixture, aldehydes are already formed during ozonolysis, and not first during reductive cleavage of the ozonides. However, increased yields of aldehydes were described only in a reductive workup with hydrogen and a metal catalyst. The water was preferably added only in the reduction step. The problem of the formation of ozonides in the ozonolysis stage remains.
- the ozonolysis processes described above have the disadvantage that they are incompatible with the conditions of the reductive amination and do not safely avoid the formation of explosive ozonides in the ozonolysis stage.
- the technical object of the invention was therefore to provide a method for Production of omega-amino acids or their esters to provide, which avoids the one hand, the formation of ozonides and on the other hand allows direct reaction of the reaction product from the ozonolysis in the reductive amination.
- This technical object is achieved by a process for the preparation of omega-amino acids or their esters, which is characterized by the following steps: a) ozonolysis of unsaturated fatty acids or fatty acid derivatives, b) reductive amination of the product obtained from the reaction with ozone
- the solvent contains 1 to 20 wt.%, Preferably 2 to 15 wt.% And particularly preferably 5 to 10 wt.% Water based on the total amount of solvent.
- fatty acids or fatty acid derivatives those having at least one double bond are used.
- Particularly preferred fatty acids and fatty acid derivatives are compounds selected from the group consisting of oleic acid, oleic acid alkyl ester, undecylenic acid, undecylenic acid alkyl ester, erucic acid, erucic acid alkyl ester.
- Petroselinic acid elaidic acid, vaccenic acid, gadoleic acid, icosenoic acid, cetoleic acid and nervonic acid and their esters. These are monounsaturated fatty acids. Furthermore, it is also possible to use polyunsaturated fatty acids, for example linoleic acid, linolenic acid, calendic acid, punicic acid, elaeostearic acid, arachidonic acid,
- Timnodonic acid clupanodonic acid and cervonic acid or their esters.
- the ozonolysis and the reductive amination are carried out directly one after the other without isolation or
- Particularly preferred solvents are a secondary or tertiary Alcohol, most preferably 2-propanol or feri. Butanol used.
- the ozonolysis is usually carried out in alcohol as
- the reaction mixture furthermore contains at least 0.5% by weight of water, based on the total amount of solvent.
- the unsaturated fatty acid ester is present in a concentration of 0.1 to 1 mol / L. If higher concentrations of fatty acid esters are used, it should be noted that the amount of added water is always chosen at least stoichiometrically to the number of double bonds reacted.
- the ozonolysis is preferably carried out at temperatures of 0 to 25 ° C.
- an ozone generator for ozone generation. This ozone generator uses as feed gas technical air or a mixture of carbon dioxide and oxygen. In the ozone generator, the ozone is produced by silent electric discharge. This oxygen radicals are formed, which react with oxygen molecules to form ozone.
- the resulting reaction mixture is fed to the reductive amination without further work-up or isolation.
- This reductive amination is preferably carried out using a Raney nickel catalyst and hydrogen.
- This reductive amination is known per se in the prior art and is carried out according to the usual
- the pressure in the reductive amination in the range of 30 to 100 bar, preferably 50 to 100 bar and the temperature in the range of 50 to 150 ° C.
- hydrogen is preferably fed to the reaction product from the ozonolysis.
- the reaction mixture from the ozonolysis is transferred to an autoclave and charged with the catalyst. After closing the autoclave, ammonia is added under pressure and hydrogen. The reaction mixture is heated and after
- the reaction produces fatty amines as well as omega- amino acids or their esters in high yields.
- the advantage of the method according to the invention is that the formation of explosive by-products such as secondary ozonides or oligomeric ozonides in the ozonolysis is avoided by the addition of water.
- the direct formation of aldehydes takes place in one reaction step without the use of further reduction equivalents such as, for example, hydrogen / catalyst, complex metal hydrides, dimethyl sulfide, triphenylphosphine, zinc / acetic acid, as is necessary in the prior art. Since the reaction mixture of ozonolysis can be further reacted immediately in the reductive amination, be
- the inventive method further allows that directly a reductive amination of the
- Reaction mixture from the ozonolysis can be performed.
- Methyl oleate (4 g, 95 wt .-% pure, 0.012 mol) is in a
- the ozone generator used is an Anseros type device, COM-AD ⁇
- the ozone generator is set to maximum performance.
- the ozone-containing gas mixture is passed with good stirring into the reaction mixture.
- the waste gas stream is passed through gas washing bottles in an approximately 5 wt .-%, aqueous potassium iodide solution. After 60 minutes, the substrate is reacted, whereupon the gas introduction is interrupted.
- the reaction mixture has a content of 39.5% by weight of 9-nonanal and 38.2% by weight of 9-oxo-nonanoic acid methyl ester.
- reaction mixture is poured into a 100 mL steel autoclave and charged with Raney Nickel (1.2 g). After closing the autoclave, ammonia (11.35 g, 0.67 mol) is added via a pressure cylinder. 70 bar of hydrogen are pressed on and heated to 80.degree. After six hours, the reaction mixture is cooled and the autoclave is depressurized. According to a GC analysis, the aldehydes were completely reacted. In this case, 46.4 wt .-% 9-aminononane and 24.0 wt .-% 9-Aminononanklaremethylester have formed.
