Definitions
- the present invention relates to N- [N- [3- (3-methyl-4-hydroxyphenyl) -3-methylbutyl] _L, which is an excellent intermediate for various productions of foods, pharmaceuticals, etc., particularly as a sweetener of high sweetness.
- — ⁇ -aspartyl] A new arylpropyl aldehyde derivative useful as a production intermediate for L-phenylalanine 1-methyl ester, its production method, its use (as a production intermediate), and a new production intermediate therefor About the body.
- the method for producing monomethyl ester is as follows. B method of removing the benzyl group protecting group after reductive alkylation Ri by the and (OA c) 3 ⁇ was considered . However, 3- (3-methyl_4-benzyloxyphenyl) -1-methylbutyraldehyde is synthesized from 3-methyl-4-hydroxyacetophenone in a seven-step reaction as shown in Reaction Step 1 below. It is not a complicated and industrially advantageous reaction substrate.
- An object of the present invention is to provide N_ [N— [3— (3-methyl-4-hydroxyphenyl) -13-methylbutyl] -1-L-hyaspartyl] —L-fe, which is excellent as a high-intensity sweetener. It is an object of the present invention to provide a method for industrially and efficiently producing dilulanine 1-methyl ester, and in particular, to provide a production intermediate therefor or a simple production method thereof. Disclosure of the invention
- the present invention includes the following contents.
- 3- (3-methyl-4-hydroxyphenyl) -1-methylbutyric acid By subjecting 3- (3-methyl-4-hydroxyphenyl) -1-methylbutyric acid to a reaction for converting a carboxyl group to a formyl group, 3- (3-methyl-4-hydroxy) (Droxyphenyl) A method for producing 3-methylbutyraldehyde.
- 3_ (3-Methyl-4-methoxyphenyl) —substitute 3-methylbutyric acid into a reaction that converts a methoxy group to a hydroxyl group;
- R is a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms
- R 2 is a lower alkyl group having 1 to 4 carbon atoms
- R 3 is a carboxyl group, a formyl group and hydroxymethyl Represents one of the groups, respectively.
- any of the following compounds are particularly suitable as intermediates for production:
- the reaction between 2-methoxytoluene and 3-methylcrotonic acid in the first step it is possible to carry out the reaction without solvent, but it is preferable to carry out the reaction in an organic solvent in the presence of an acid.
- the organic solvent used is not particularly limited as long as it is inert to the reaction substrate, acid and reaction product.
- any of a protic acid such as sulfuric acid, paratoluenesulfonic acid, and hydrogen chloride
- a Louis acid such as aluminum chloride and titanium tetrachloride can be used.
- more than one acid can be used for each protonic or Lewis acid.
- a protonic acid and a Lewis acid may be used in combination, if necessary, such as using hydrogen chloride and aluminum chloride in combination.
- Use of an acid adhered on a solid phase is also a desirable method because the treatment step is simplified.
- the amount of the acid used is not particularly limited, and the reaction can be completed in a short time if used in a large excess with respect to 3-methylcrotonic acid. However, from an economic viewpoint, it is preferable to use 3-methylcrotonic acid. It is 5 equivalents or less, more preferably 3 equivalents or less, and still more preferably about 0.1 to 3 equivalents.
- the amount of 2-methoxytoluene used for 3-methylcrotonic acid is not particularly limited, but is preferably 0.5 equivalent or more, more preferably 1 equivalent or more, and more preferably 3-methylcrotonic acid. It is preferably about 1 to 10 equivalents.
- the reaction temperature is not particularly limited, but the higher the temperature is, the more the side reaction proceeds, and the lower the temperature is, the slower the reaction rate becomes.Therefore, the reaction temperature is preferably about 120 to 180 ° C, more preferably about 120 to 180 ° C. — About 10 to 100 ° C, more preferably about 0 to 70 ° C.
- 3— (3— Methyl-4-methoxyphenyl) 1-3-methylbutyric acid can be easily converted to a hydroxyl group, for example, by heating in an acidic aqueous solution.
- the acid used include hydrogen chloride, hydrogen bromide, and sulfuric acid, and the reaction temperature is particularly limited. However, about 80 to 150 ° C. is preferably used.
- the desired 3- (3-methyl-4-hydroxyphenyl) -3-methylbutyric acid obtained by the above reaction by the third step of converting a carboxyl group into a formyl group the By reduction, the desired 3- (3-methyl-4-hydroxyphenyl) -3-methylbutyraldehyde can be obtained.
- the desired 3- (3-methyl-4-hydroxyphenyl) is preferably directly half-reduced by the method described in Chemistry Letters, published in January 1998, page 1143-1144. ) Can be converted to 3-methylbutyraldehyde.
- This method involves reducing 3- (3-methyl-4-hydroxyphenyl) -3-methylbutyric acid with hydrogen in an organic solvent, adding vivalic anhydride, palladium acetate and a triphenylphosphine derivative. is there.
- the organic solvent to be used is not particularly limited as long as it is an inert solvent for the reaction substrate, the catalyst and the product. Acetone, tetrahydrofuran (THF), toluene and the like are preferably used.
- the amount used should be at least equimolar to 3- (3-methyl-4-hydroxyphenyl) -1-methylbutyric acid, and about 1 to 5 times the molar amount is preferably used.
- triphenylphosphine @ tolylphosphine is preferably used. Since palladium acetate and triphenylphosphine derivatives are used as catalysts, the use amount of about several mole percent is sufficient.
- the reaction temperature used in the reaction is not particularly limited, but it is more advantageous to carry out the reaction at a relatively high temperature, since a higher temperature promotes the reaction and allows the reaction to be completed in a short time.
- the carboxyl group is completely reduced to a hydroxymethyl group, and then the desired aldehyde derivative is produced by partial oxidation. You can also.
- the above-mentioned target compound can be easily produced by a known partial reduction oxidation (see Journal of Organic Chemistry, vol. 8, No. 25, 5043-5048, 1983).
- a reductive alkylation catalyst for example, a hydrogenation catalyst such as a palladium-based or rhodium-based catalyst
- the alkylation reaction is carried out reductively with hydrogen in the presence, and more preferably the above-mentioned target compound can be produced under an appropriate or effective reaction temperature and pressure.
- N is useful as a high-intensity sweetener by a reductive alkylation reaction with aspartame.
- N [3- (3-Methyl-4-hydroxyphenyl) -1-methylbutyl] — L- ⁇ -aspal [Chill] _L-phenylalanine 1-methyl ester can be produced industrially simply and efficiently.
- the above aldehyde derivative is a novel compound, but converts 3- (3-methyl-4-methoxyphenyl) -3-methylbutyric acid obtained by the reaction of 2-methoxytoluene and 3-methylcrotonic acid into methoxy group to hydroxyl group
- the carboxylic acid can be easily and efficiently produced by a reaction of converting a carboxyl group of the obtained carboxylic acid into a formyl group.
- Sweeteners can be produced industrially advantageously.
