AI Technical Summary

Technical Problem

Existing technologies struggle to effectively construct chiral α,α-diaryl ketone compounds with stereoselectivity because the α-H group is affected by the carbonyl group and is prone to racemization under basic or acidic conditions, making stereoselectivity difficult to control.

Method used

A photocatalytic process was used to form quinone intermediates. Chiral α,α-diaryl ketones were prepared by reacting alkyne compounds and benzoquinone with a chiral phosphoric acid catalyst under visible light irradiation using commercially available compounds 1, 2, and 3. The reaction temperature was controlled between -78℃ and 25℃. Molecular sieves were added to reduce the water content of the system and improve enantioselectivity.

Benefits of technology

It enables the preparation of chiral α,α-diaryl ketones with high yield and enantioselectivity, and is applicable to the modification of natural product molecules and the stereoselective synthesis of drug molecules.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic synthesis, and particularly to a chiral α, α-diaryl ketone compound, a preparation method and application thereof. BACKGROUND

[0002] The α, α-diaryl ketone molecular skeleton is widely present in many natural products with important biological activities, organic functional materials and artificially synthesized drug molecules. For example, Pauciflorol E isolated from the stems of Styrax benzoin, Penchinones C and Penchinones D isolated from the liver-protecting decoction of Radix Pteroxygoni Multifidi and Volixibat Pharmacophore used for treating tuberculosis. Limited to the difficulty in preparation of the product and the possible racemization during the carbonyl addition reaction or storage, there are few effective methods to construct this specific skeleton with enantioselectivity, because the α-H is affected by the carbonyl group and shows quite strong acidity, leading to enolization under alkaline or acidic conditions to initiate racemization, and this inherent property makes it extremely difficult to control the stereoselectivity.

[0003] Therefore, it is necessary to develop a series of new chiral α, α-diaryl ketone compounds. SUMMARY

[0025] The prior art is difficult to prepare and racemization may occur in the process after the carbonyl addition reaction or the reaction is completed, and there are few effective methods to construct this specific skeleton with enantioselectivity, because the α-H is affected by the carbonyl group, which shows quite strong acidity, leading to enolization under basic or acidic conditions to initiate racemization, and this inherent property makes it extremely difficult to control stereoselectivity.

[0142] Synthesis of pyridinamide analogs

[0143] Florylpicoxamid is the second generation pyridinamide fungicide developed by Dow AgroSciences, which can be used for the prevention and treatment of diseases caused by Cylindrocarpon, Erysiphe, Monilinia, Alternaria fungi and powdery mildew, anthracnose, spot disease, etc. in cereals, grapes, fruit trees, nuts, vegetables, etc. It acts on the complex III Qi ubiquinone (i.e. coenzyme Q) bonding site of fungi, and inhibits mitochondrial respiration to produce effect.

[0144] The present application successfully realizes the asymmetric synthesis of the drug through a series of reactions, and the synthesis route is as follows:

[0145]

[0146] The preparation steps are as follows:

[0147] Under the protection of nitrogen at room temperature, aryl alkyne compound 1 (4 mmol, 2.0 equiv) and benzoquinone (2 mmol, 1.0 equiv) were dissolved in CH2Cl2(40 mL) solution, irradiated under blue LED (2x35W) for 4h, then the reaction mixture was cooled to-60℃, and MS (1.2g), (R)-C11 (0.1mmol, 5mol%) and compound 2-6 (3mmol, 1.5equiv) were added to the system in turn. The resulting mixture was stirred at-60℃ for 3h. After the reaction was completed, the mixture was concentrated under vacuum, and directly subjected to silica gel column chromatography (eluent: petroleum ether / ethyl acetate = 3:1) to obtain compound I-102;

[0148] To the methanol (16mL) solution of compound I-102 (390.8mg, 1.6mmol) at 0℃, NaBH4 (90.8mg, 2.4mmol) was added. The reaction mixture was stirred at room temperature for 1h, and after the reaction was completed, DCM was extracted. The organic layer was dried over Na2SO4, concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: petroleum ether / ethyl acetate / dichloromethane 3:1:3 to 1:1:1) to obtain products I-103 and I-103';

[0149] To a solution of compound I-103 (123.1 mg, 0.5 mmol) in CH2Cl2(5 mL) was added Et3N (105 ul, 0.75 mmol), 4-methylbenzenesulfonyl chloride (114.4 mg, 0.6 mmol) sequentially at 0 °C and stirred for 1 h at 0 °C. After the reaction was completed, the mixture was concentrated in vacuo and directly subjected to silica gel column chromatography (eluent: petroleum ether / ethyl acetate 2:1) to give compound I-104.

[0150] To a solution of compound I-104 (195 mg, 0.49 mmol), DMAP (6 mg, 0.049 mmol), (S)-2-((tert-butoxycarbonyl)amino)propanoic acid (111.3 mg, 0.588 mmol) in CH2Cl2(5 mL) was added l-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI) (187.9 mg, 0.9 mmol) at 0 °C. The reaction was stirred at room temperature for 12 h. It was concentrated in vacuo and directly subjected to silica gel column chromatography (eluent: petroleum ether / ethyl acetate 1:1) to give compound I-105;

[0151] To a solution of compound I-105 (171.5 mg, 0.3 mmol) in 1,4-dioxane (2 mL) was added HCl (1 mL, 4 mol, 4 N) at room temperature. The reaction was stirred overnight and then concentrated in vacuo to give a sticky material. After the addition of diethyl ether (10 mL), the mixture was stirred vigorously for 30 min. The mixture was filtered, rinsed with diethyl ether, and then rinsed with n-hexane. The crude product, alanine hydrochloride, was dried in vacuo. To a mixture of alanine hydrochloride, 3-hydroxy-4-methoxypicolinic acid I-106 (55.8 mg, 0.33 mmol) in DCM (3 mL) was added PyBOP (171.7 mg, 0.33 mmol) and N,N-diisopropylethylamine (183 uL, 10.5 mmol). The reaction was stirred at room temperature for 24 h. After it was concentrated in vacuo, it was directly subjected to silica gel column chromatography (eluent: petroleum ether / ethyl acetate 1:2) to give the product I-107 as a white foamy solid.

[0152] To a 25 mL flask was added compound I-107 (62.3 mg, 0.1 mmol), triethylamine (0.5 mL), and acetic anhydride (0.5 mL, 5 mol). It was stirred at room temperature for 1 h. After it was concentrated in vacuo, it was directly subjected to silica gel column chromatography (eluent: petroleum ether / ethyl acetate 1:1) to give the product I-108.
