Abstract
General structure (1) show novel chiral N, the N ligand based on ferrocene frame having ferrocene frame, wherein R1For the alkyl of C1-C7, aryl or substituted aryl, R2For hydrogen or the alkyl-substituted silylation of C1-C7, R3For hydroxyl or the alkoxy of C1-C7, R4For hydrogen, the alkyl of C1-C7, aryl or substituted aryl, the substituted group is selected from phenyl, benzyl, naphthalene, the alkyl of C1-C7, the alkoxy of C1-C7, halogen, nitro, hydroxyl.The present invention is raw material using ferrocene cheap and easy to get, prepare novel N by easy synthetic route, N ligand, introduces multiple chiral factors in this ligand, and introduce hydrogen-bond donor, the fine structures such as steric hindrance and electronic effect are with good adjustability.
Description
Technical field
Novel chiral N, N ligand the present invention relates to one kind based on ferrocene frame having ferrocene frame belongs to asymmetry catalysis synthesis field.
Background technique
In numerous chiral skeletons for constructing ligand, ferrocene because its high heat stability, chemical stability and easily
It the features such as modification and special electronic effect, spatial chemistry, is widely used in asymmetric catalysis.Two
The type of luxuriant iron ligand is varied, can be subdivided by different the position of substitution, the number of substituent group and coordination atom difference
Different types of ligand.
In developed ferrocene chiral ligand, the overwhelming majority be biphosphine ligand and phosphine-hetero atom bidentate ligand, typically
Example such as Walphos, Chenphos and TriPhos etc..Related ferrocene is the chiral N of skeleton, and the report of N- ligand is but extremely
It is rare.It is well known that N, N- ligand because its stability, it is convieniently synthesized, be widely used the features such as one in asymmetric catalysis field
Directly it is concerned.
Summary of the invention
The purpose of the present invention is to provide a kind of raw materials to be easy to get, convieniently synthesized, catalytic activity is high, chiral induction acts on strong
Ferrocene N, N- ligand, such ligand include multiple chiral factors, and there is also potential hydrogen-bond donors, in the reaction can be the bottom of with
Object forms secondary interaction and further stablizes reaction transition state, is a kind of efficient novel chiral N, N- ligand.
It is a further object of the present invention to provide the preparation methods of above-mentioned ligand.
It is a still further object of the present invention to provide above-mentioned ligands and palladium original position composition catalyst in asymmetry catalysis allyl
Application in base substitution reaction.
Realization process of the invention is as follows:
Ferrocene frame having ferrocene frame chirality N, N ligand shown in general structure (1),
(I)
R1For the alkyl of C1-C7, aryl or substituted aryl;
R2For hydrogen or the alkyl-substituted silylation of C1-C7;
R3For hydroxyl or the alkoxy of C1-C7;
R4 For hydrogen, the alkyl of C1-C7, aryl or substituted aryl;
The substituted group be selected from phenyl, benzyl, naphthalene, the alkyl of C1-C7, the alkoxy of C1-C7, halogen, nitro,
Hydroxyl.
Specifically, R1For methyl, isopropyl, tert-butyl, cyclohexyl, phenyl, 2,4 dichloro benzene base, benzyl, adamantane
Base;R2For trimethylsilyl or hydrogen;R3For methoxyl group or hydroxyl;R4 Middle aryl is selected from phenyl, benzyl, naphthalene, the alkane of C1-C7
The aryl that base, the alkoxy of C1-C7, halogen, nitro, hydroxyl replace.
The inductive structure of typical ferrocene N, the N- ligand in part is as follows:
The preparation method of above-mentioned ferrocene frame having ferrocene frame chirality N, N ligand, comprising the following steps:
(1) using ferrocenecarboxylic acid as raw material, with chiral amino alcohol in the presence of triphenylphosphine, carbon tetrachloride, triethylamine,
Generate ferrocene-oxazoline class compound;
(2) ortho lithiation occurs under that action of n-butyl lithium for above-mentioned ferrocene-oxazoline compound, with trimethylchloro-silicane
Alkane effect generates key intermediate;
(3) pyridine carboxaldehyde or substituted pyridines formaldehydes are added under that action of n-butyl lithium again after lithiumation in above-mentioned intermediate
Compound generates ferrocene class N, N- ligand through column chromatography for separation.
Synthetic route is as follows:
Ferrocene frame having ferrocene frame chirality N, N ligand of the present invention can be applicable in the allyl group alkylated reaction of palladium chtalyst.
Two building blocks of oxazoline and pyridine are dexterously assembled in ferrocene in Catalyst Design of the invention by inventor
On skeleton, a kind of novel ferrocene N, N- ligand is formed, while introducing a potential hydrogen-bond donor, the latter is as Louis
This acid, the hydrogen bond that can be formed between the hydrogen bond receptor in related substrates, this secondary interaction force are living to the catalysis of reaction
Property and stereoselectivity play a crucial role.In addition, by the unique stereoeffect of ferrocene frame having ferrocene frame, in such ligand

Base }-(2- pyridyl group)-methanol 1 and (S)-{2-[(S) -4- isopropyl -4,5- dihydro-oxazole base] -3- (trimethylsilyl) benzene
Base }-(2- pyridyl group)-methanol 1 '
Step 1:
Ferrocenecarboxylic acid (3.10g, 13.5 mmol) are added in 250mL single port bottle, after evacuated/inflated with nitrogen circulation,
Dry methylene chloride 25mL is added, draws oxalyl chloride (2.40mL, 27.0 mmol) with syringe and stirs at room temperature, reaction has
Gas is released, and reaction solution becomes peony after 20 m, is continued after stirring 10 m, revolving removes solvent, obtained brown-red solid
Be directly dissolved in 15mL methylene chloride, be added to after long needle aspirate (S)-valerian ammonia alcohol (1.65g, 16.11 mmol) and three
In the dichloromethane solution of ethamine (3.75 mL, 27.0 mmol), under nitrogen protection, it is stirred overnight at room temperature, gained dark-brown
Mixture washes (2 x, 30 mL), anhydrous Na2SO4Dry, gained crude product column chromatographic purifying obtains yellow solid 3.6g, produces
Rate 84%.
In the acetonitrile solution of yellow solid obtained above (2.45 g) and triphenylphosphine (7.47 g) (60 mL), add
Enter triethylamine (4.8 ml) and carbon tetrachloride (6.6mL), gained mixture are stirred overnight at room temperature under nitrogen protection, adds 80mL water
It is quenched, petroleum ether extraction (5 x, 50 mL), merges organic phase, anhydrous MgSO4Dry, crude by column chromatography purifies to obtain phase
Ferrocene-the oxazoline answered is light yellow solid, total 2.04g, yield 89%.
Step 2:
Take the history Nike pipe that ferrocene-oxazoline obtained in step 1 (2.04g, 6.86 mmol) is dry in a 100mL
In, it vacuumizes, inflated with nitrogen, is added dry ether (20mL), is cooled to 0 DEG C, carefully draws n-BuLi (1.6M with long syringe needle
Hexane solution, 4.72 mL, 7.55 mmol) it is slowly added to above-mentioned reaction tube, after stirring 1h at 0 DEG C, drawn with syringe
Trimethylsilyl chloride (0.96mL, 7.55 mmol) is warmed to room temperature naturally after stirring 1h at 0 DEG C, and anhydrous ether dilution is added
Reaction solution, a small amount of water quenching reaction separate organic layer, anhydrous Na2SO4Dry, revolving removes solvent, and column chromatographic purifying there are tangerine
Red solid 2.2g, yield 87%.
Step 3:
It takes the above Chinese red solid powder (2.0g, 5.41 mmol) in one 100 mL dry history Nike pipe, takes out true
Anhydrous THF (15 mL) is added in sky, inflated with nitrogen, be slowly added under -78 °C n-BuLi (1.6M hexane solution, 3.72
ML, 5.95 mmol), at this temperature stir 1h after, in this reaction tube be added 2- pyridine carboxaldehyde (0.57 mL, 5.95
Mmol), after reacting 2h at the same temperature, reaction solution is slowly increased to room temperature and is stirred overnight, and is quenched with 2mL methanol, revolving is removed
Solvent is removed, column chromatographic purifying respectively obtains target product 1, is crocus solid, total 976mg, yield 38%;Obtain target production
Object 1 ' is Chinese red solid, total 1.03g, yield 40%.
