Definitions
- the present invention relates to a shortened process for the production of L-lobeline by rhodium-catalyzed asymmetric hydrogenation on an industrial scale.
- Lobelin is one of the lobelia alkaloids of Lobelia inflata (Indian tobacco, weevil, asthma grass) and is native to the eastern and central states of the USA and Canada. The plant contains about 0.3% alkaloids.
- the lobelia alkaloids are 2,6-disubstituted piperidine derivatives.
- Lobelin is the main alkaloid.
- Lobelin has a parenteral (3-10 mg) respiratory stimulant and was formerly used as a respiratory analeptic in asthma, collapse and the like. Anesthesia accidents given. Orally taken, it is degraded rapidly and is therefore ineffective. Because lobeline potentiates the effect of nicotine and thus causes nausea and disgust, it is clinically developed in depot form as a smoking cessation drug (Drug News (25.3) 1996, 6).
- the object of the present invention is thus to provide a shortened process for the production of L-lobeline.
- lobeline of the formula I can be obtained on an industrial scale in good yields and good optical purity by subjecting a corresponding diketone II to asymmetric hydrogenation in the presence of rhodium and a chiral, bidentate phosphine ligand as the catalyst system.
- the present invention relates to a process for the preparation of L-lobeline, of the formula I,
- the starting material of formula II can be obtained by simply reacting 3-oxo-3-phenylpropionic acid, 1,5-pentanedione and methylamine hydrochloride in acetone and in the presence of a citrate buffer.
- 3-Oxo-3-phenylpropionic acid is obtainable by saponification of the corresponding ethyl ester.
- inert diluents it is possible to use both protic solvents - such as, for example, alcohols and / or water - or aprotic polar solvents such as, for example, ethers and / or amides or lactams and / or mixtures thereof. All solvents may optionally be added with water.
- the protic solvents used are preferably branched or unbranched C 1-8 -alcohols . Particular preference is given to using lower alcohols such as methanol, ethanol, n-propanol and zs ⁇ -propanol or mixtures thereof. Methanol is particularly preferably used as the reaction medium, it being possible for the methanol or the other alcohols or solvents lo to optionally contain water.
- aprotic solvents are polar ethers such as tetrahydrofuran or dimethoxyethyl ether or amides such as dimethylformamide, or lactams such as N-methylpyrrolidone. Preference is given to using solvents which have little tendency to combustibility.
- a weak base selected from the group of tertiary amines, alkali metal hydrogencarbonates and alkali metal carbonates.
- Suitable organic bases are tertiary amines, in particular tertiary alkylamines, tertiary alkyl-arylamines or pyridines. Preference is given to using trialkylamines having branched or unbranched C 1-6 -alkyl radicals. Triethylamine or diisopropylethylamine have proven to be very particularly preferred, for example.
- the reaction can also be carried out in the presence of basic polymers with, for example, tertiary amino functions.
- the asymmetric hydrogenation is carried out in a temperature range from 0 ° C to 100 ° C, preferably 20-80 ° C, particularly preferably 40-60 0 C 0.
- the above process in which the asymmetric hydrogenation is carried out under a pressure of 1 to 40 bar, preferably 10 to 30 bar, more preferably 15 to 25 bar.
- the process is carried out under a protective gas atmosphere, preference being given to nitrogen or argon atmosphere, or mixtures thereof.
- Heating the reaction mixture to 20-80 ° C., preferably 40-60 ° C., more preferably 47-53 ° C. and adjusting the hydrogen pressure to 10-30 bar, preferably 15-25 bar, particularly preferably 20 bar,
- the work-up of the reaction can be carried out in a customary manner, for example by deactivating and separating off the catalyst if appropriate, removing the solvent from the residue by isolating pure end product by crystallization, distillation, extraction or chromatography. Preference is given to a process in which the following steps are carried out to isolate the product:
- step (ix) is crystallized by addition of a -Ci -8- alcohol, preferably w-propanol.
- C 1-8 -alcohol is understood to mean branched and unbranched alcohols having 1 to 8 carbon atoms and one or two hydroxyl groups. Accordingly, the term “C 1-4 alcohols” is understood to mean branched and unbranched alkyl groups having 1 to 4 carbon atoms and one or two hydroxyl groups. Preferred are alcohols having 1 to 4 carbon atoms.
- Examples include: methanol, ethanol, n-propanol, zso-propanol, n-butanol, w ⁇ -butanol, sec-butanol, tert-butanol, n-pentanol, zso-pentanol, 7ieo-pentanol or hexanol. If necessary, be for The above-mentioned molecules also use the abbreviations MeOH, EtOH, / i-PrOH, / -PrOH, n-BuOH, / -BuOH, t-BuOH, etc.
- propanol, butanol, pentanol and hexanol include all conceivable isomeric forms of the respective radicals.
- propanol includes 7z-propanol and / jo-propanol
- butanol includes w ⁇ -butanol, sec-butanol and tert-butanol, etc.
- the compounds of formula I and II can be converted into their acid addition salts with an inorganic or organic acid.
- suitable acids are succinic acid, hydrobromic acid, acetic acid, fumaric acid, maleic acid, methanesulfonic acid, lactic acid, oxalic acid, phosphoric acid, hydrochloric acid,
- Sulfuric acid, tartaric acid or citric acid into consideration. Furthermore, mixtures of the abovementioned acids can be used.
- the catalyst solution is metered into the autoclave and then charged with hydrogen of 4 bar. Drain the excess pressure in the vacuum pump. Repeat this process 4 times. Heat the autoclave contents to 47-53 0 C, set the hydrogen pressure to 20 bar, and set the stirrer to maximum speed. At 120% hydrogen uptake of the theory (130.1 bar) stop the hydrogenation. Cool the autoclave contents to 20-25 ° C. Then evacuate the autoclave (700 mbar) and adjust with nitrogen. Transfer the hydrogenation solution into a 500 1 stirrer apparatus and distill off the methanol under reduced pressure at 50-60 ° C (towards the end of the distillation at 45-50 0 C).
