Definitions
- the present invention relates to a new process for preparing vitamin A as well as to new intermediates obtained during the implementation of this process.
- the present invention has made it possible, starting from ethynyl retro- ⁇ -ionol, to reach directly, without passing through the carbonate intermediate, an allenic derivative. This reaction is carried out in the presence of a metal catalyst.
- the present invention relates to the preparation of an intermediary for vitamin A in C15 of formula:
- the preparation of propargylic acetate is carried out by bringing together ethynyl retro- ⁇ -ionol with acetic anhydride or acetyl chloride in the presence of a tertiary amine. It is preferred to use as tertiary amine triethylamine, trimethylamine, tributylamine, pyridine. An activating agent such as dimethylamino pyridine is preferably added. The amount of activating agent which is used is preferably between 1 and 5% calculated in molar equivalent relative to the alcohol. It is preferred to work in an inert solvent which is chosen in particular from aliphatic or aromatic solvents, optionally halogenated.
- the second step which consists in isomerizing the propargylic acetate obtained in the previous step is carried out in the presence of a metallic catalyst based on copper according to the following reaction scheme:
- cuprous chloride It is preferred to use cuprous chloride.
- a molar ratio of the cuprous salt to the propargyl acetate is used between 0.5% and 5% and preferably about 1%.
- the reaction solvent is preferably chosen from esters and optionally halogenated aliphatic or aromatic solvents. We prefer to use monochloro benzene.
- the optimal concentration of propargylic acetate in the reaction solvent is between 0.1 and 1 mole per liter and is more preferably around 0.5 mole per liter.
- the temperature conditions are chosen within limits which do not lead to the degradation of propargylic acetate. It is preferred to work at temperatures between 100 and 150 ° C and preferably at about 100 ° C.
- the following step consists in hydrolyzing the allene acetate to the corresponding aldehyde according to the following reaction:
- the isomerization and deacetylation catalyst is a mineral acid chosen in particular from hydrochloric acid, hydrobromic acid or sulfuric acid. It is preferred to use hydrobromic acid in acetone.
- vitamin A is prepared according to a known process.
- Vitamin A may be cited among the known processes the patent FR 2 707 633 which, by condensation with a lithium or potassium salt of prenal dienolate provides a dihydropyranic intermediate which by gentle hydrolysis in the presence of a weak acid leads to the retinal
- the present invention also relates to a process for the preparation of vitamin A from ⁇ ionone.
- This process consists in a first step in isomerizing the ⁇ ionone into retro ⁇ ionone in the presence of potassium terbutylate in dimethylsulfoxide such as for example described by Cerfontain in Synthetic Communications, 1974, 4 (6), 325-30.
- This process more generally concerns the isomerization of ⁇ ionone with a strong base chosen from alkali alcoholates or alkali hydroxides in a polar aprotic solvent.
- the alkali alcoholate is preferably sodium methylate
- the alkali hydroxide is preferably sodium hydroxide, potassium hydroxide, lithium hydroxide, calcium or barium hydroxides.
- the solvent is in particular chosen from dimethylsulfoxide, N methylpyrrolidone or dimethylformamide.
- a molar ratio between the strong base and the ⁇ ionone between 1 and 1.5.
- the second step consists in carrying out an ethynylation of the retro ⁇ ionone obtained previously according to the following reaction scheme:
- This step is carried out in the presence of lithium or magnesium acetylide. It is preferred to use magnesium acetylide formed in situ by contact of acetylene with isopropyl magnesium choride. It is preferred to use ethers, polar solvents such as aromatic solvents, as solvent, it is very particularly preferred to use tetrahydrofuran.
- the reaction temperature is preferably lower than room temperature. It is in particular between -10 ° C and ambient temperature. The reaction is preferably carried out in a solvent chosen from ethers, polar solvents such as aromatic solvents, it is very particularly preferred to use tetrahydrofuran.
- ethynyl ⁇ retro ionol obtained is then acetylated in accordance with the first step of the first process according to the invention, propargylic acetate obtained is according to the overall process for the preparation of vitamin A condensed with a methyl 1 butadiene derivative according to the following reaction scheme:
- R represents a linear or substituted C1-C4 alkyl group, a linear or substituted C1-C4 acyl group or a trialkylsilyl or triarylsilyl group. It is preferred to use acetyl methyl 1 butadiene or 3 trimethylsilyl oxy 1 methyl butadiene.
- the condensation reaction is preferably carried out in the presence of a Lewis acid chosen in particular from zinc chloride, titanium tetrachloride, boron trifluoride, trityl salts (perchlorate, tetrafluoro borate).
- a solvent chosen from polar solvents such as nitroalkanes or chlorinated solvents.
- This reaction is carried out in the presence of an acid in a ketone solvent or in an aromatic solvent, in particular halogen.
- the isomerization catalyst is chosen from mineral acids such as in particular hydrochloric acid, hydrobromic acid or sulfuric acid. It is preferred to use hydrobromic acid in acetone. According to a better way of implementing the invention, it is preferable to use 0.25 to 0.5 equivalent of hydrobromic acid per mole of C20 allenic derivative to be isomerized.
- the table above means by TT the rate of transformation of the initial product, that is to say from prenyl acetate, and by RR, the actual yield of the reaction, that is to say the quantity of product obtained over the quantity of reagent introduced.
- Test 1 - 4914 mg of beta-ionone are poured onto a suspension of 1773 mg of sodium methylate in 23 ml of NMP, in 34 min, at 3 ° C. After 70 min after the end of casting, the conversion is complete. Poured onto 100g of ice and extracted with 2 times 50 ml of ethyl ether, dried over magnesium sulfate and concentrated. 88% of retro-alpha-ionone are thus recovered for a 99% conversion of beta-ionone.
- Test 2 4982 mg of beta-ionone are poured onto a suspension of 1061 mg of sodium hydroxide in 23 ml of NMP, in 32 min, at 5 ° C. After 3.30 p.m. after pouring, pour onto 100g of ice and extract twice with 50ml of ether ethyl, dried over magnesium sulfate and concentrated. 64% of retro-alpha-ionone is thus recovered, for a 88% beta-ionone conversion.
- Test 3 4923 mg of beta-ionone are poured onto a suspension of 1813 mg of potassium hydroxide in 23 ml of NMP, in 32 min, at 5 ° C. After 6:30 am after the end of pouring, pour onto 100g of ice and extract with twice 50 ml of ethyl ether, dry over magnesium sulphate and concentrate. 83% of retro-alpha-ionone are thus recovered, for a conversion of beta-ionone of 96%.
