Definitions
- the present invention relates to a method for producing a 2-alkenylamine compound typified by allylamine. More specifically, the present invention relates to a production method capable of obtaining a 2-alkenylamine compound with high efficiency by reacting a compound having an amino group with a 2-alkenyl compound in the presence of a specific transition metal complex and a ligand.
- 2-Alkenylamine compounds represented by allylamine have a hetero atom (nitrogen atom) and an olefin moiety (carbon-carbon double bond) that can be converted into a functional group, and provide useful building blocks for organic synthesis. Therefore, it is widely used as bioactive functional molecules such as pharmaceuticals and agricultural chemicals, polymer modifiers, chemical reaction catalysts, and the like.
- Patent Document 1 a method of synthesizing allyl chloride with aqueous ammonia is known (Patent Document 1).
- this method three allyl compounds of monoallylamine, diallylamine, and triallylamine are produced, and the yield of the target product is reduced by side reaction (byproduct of allyl alcohol).
- side reaction byproduct of allyl alcohol.
- the same stoichiometric amount of salt as the product is generated, and the environmental load is large because halide is used as a raw material.
- this method is not preferable because the organic chlorine compound always remains in the allyl compound and has a drawback that the insulating properties are lowered when used in some applications such as electronics.
- Non-Patent Document 1 reports that allylation is performed using allyl acetate as an allylating agent, N, N-diformylamide as a substrate and a palladium catalyst.
- amine itself N, N-diformylamide
- N, N-diformylamide is weak in nucleophilicity, requires a strong base for conversion to lithium salt or sodium salt, has low reactivity, and requires a long time for allylation.
- Non-Patent Document 2 describes an asymmetric allylation method using a catalyst having benzylamine as a substrate, palladium as a central metal, and a bidentate optically active phosphite-thioether compound as a ligand. .
- Non-Patent Document 3 discloses a method for producing allylamines using allyl carbonate as an allylating agent and using a neutral rhodium complex. The reaction proceeds at room temperature in THF solvent using trimethyl phosphite as a ligand.
- amine nucleophiles need to be anionized with a stoichiometric or higher base after being protected with toluenesulfonic acid to enhance its reactivity, and the reaction is essentially under strongly basic conditions. Will be implemented. Since the ligand and amine equivalent anion are unstable to oxygen and moisture, it can be said that they are not suitable for mass synthesis.
- Non-Patent Documents 4 to 6 As an example using an iridium catalyst, methods for allylating an amine with allyl carbonate or allyl acetate, which are allylating agents, are reported in Non-Patent Documents 4 to 6, for example.
- the yield is also high, and the desired allylated product is obtained for both aliphatic amines and aromatic amines.
- allyl carbonate is used as the allylating agent, decarboxylation and elimination of alcohol such as methanol are the driving forces for the reaction.
- the generation of gas such as carbon dioxide in the co-product is problematic in terms of safety.
- iridium and (chiral) phosphoramidite ligands are required for the catalyst, and there are significant disadvantages in terms of cost.
- a base such as triazabicycloundecene (TBD) or triethylamine is stoichiometric. An amount is required.
- Non-Patent Document 7 discloses an allylation method using allyl carbonate as an allylating agent and a neutral ruthenium complex having a cyclopentadienyl anion as a complexing agent as a catalyst. The reaction is completed in 1 hour at 0 ° C. in a THF solvent. A highly nucleophilic piperidine is used as the amine, and its applicability to other substrates is unclear.
- Non-Patent Document 8 discloses a method for producing allylamines using a dicationic ruthenium complex. The reaction proceeds in a solvent at room temperature using a catalyst having a pentamethylcyclopentadienyl anion as a complexing agent, bipyridine as a ligand, and a hexafluorophosphate anion as a counter cation. These are pioneering results showing the reactivity of ruthenium complexes to allylation, but both have low reactivity, a large amount of catalyst must be used, and decarboxylation type allylating agent is used. Industrial problems cannot be avoided.
- Patent Document 2 and Non-Patent Document 9 disclose a method for producing allylamine from allyl alcohol using a phosphonoamidite ligand and an iridium catalyst.
- a primary branched allylamine can be selectively obtained using allyl alcohol as an allylating agent and sulfamic acid as an amine source.
- Patent Document 3 discloses a method for producing allyl ethers in the presence of a cyclopentadienyl ruthenium complex having an ⁇ -imino acid type ligand or an ⁇ -amino acid type ligand. According to this method, allyl ether can be produced dehydratingly from allyl alcohol and alcohol without using any additive. The only co-product is water, which is a very efficient method in harmony with the environment. However, when applied to amines, the basicity of the substrate prevents the ligand necessary for catalyst activation. It is thought that protonation is suppressed and the performance of the catalyst itself is lost. For this reason, it is considered that the allylation reaction with a basic compound does not proceed, and application to such a compound has been forgotten.
