Definitions
- the present invention relates to the field of ligand chemistry, and in particular to asymmetric hydrogenation of quinone-keto acids.
- Asymmetric hydrogenation of hydrazine-keto acids has rarely been reported in the art, and direct asymmetric hydrogenation of hydrazine-keto acids using metal ligand complexes has been reported to be largely blank in this field.
- the reason for the analysis is that the carboxyl group of the oxime-keto acid compound is complexed with the metal to poison the catalyst and lower the reaction yield; and since the fluorenylcarbonyl group of the fluoren-keto acid compound is substantially coplanar with the carboxylic acid carbonyl group, The chances of attacking the chiral ligand catalyst ketone acid compound on both sides are equal, resulting in low reaction yield or corresponding selectivity.
- the chiral spiropyridinium phosphine ligand complex with the following structure was first developed by Nankai University.
- the present invention provides the following technical solutions:
- R 1 is phenyl, substituted phenyl, naphthyl, substituted naphthyl, C 1 -C 6 alkyl or aralkyl; said substituent is C 1 -C 6 alkyl, C 1 -C 6 alkoxy a group, a halogen; the number of the substituents is 1-3.
- M is a chiral spiropyridinium phosphine ligand ruthenium complex having the following structure:
- R is hydrogen, 3-methyl, 4- t Bu or 6-methyl.
- the base is selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium t-butoxide and potassium t-butoxide.
- the molar ratio of the compound to the substrate A is (1.0 to 3):1; the preferred molar ratio is (1.001 ⁇ ). 1.5): 1.
- the solvent is selected from the group consisting of methanol, ethanol, propanol, isopropanol, tetrahydrofuran, toluene, methyl tert-butyl ether, dioxane, DMF, and the like.
- Preferred R 1 is phenyl, substituted phenyl, naphthyl, substituted naphthyl.
- the present invention adopts the following technical scheme: under nitrogen protection, the hydrogen pressure is 0.5-10 MPa, the amount of the base is 1.0-3.0 molar equivalent, and in the organic solvent, the a-keto acid A compound is in the range of 0.00001-0.01 molar equivalent.
- the B compound is obtained by catalyzing the spiropyridinium phosphine ligand complex (M).
- a substrate A 1.0 to 3 molar equivalents of sodium hydroxide, potassium hydroxide, sodium t-butoxide or potassium t-butoxide, 0.0001 to 0.01 molar equivalents of catalyst M are added to the hydrogenated inner tube. And solvent.
- the reaction inner tube was charged into a high pressure reaction vessel, and the pressure of hydrogen was hydrogenated to 0.5 to 10 MPa, and the mixture was stirred at 10 to 90 ° C for 1 to 30 hours to obtain a product B.
- the invention realizes the direct asymmetric catalytic hydrogenation of a-keto acid by changing the amount of the base used in the reaction to overcome the strong coordination of the carboxyl group and the central metal in the substrate molecule.
- Figure 1 is an optical purity HPLC chromatogram of the compound 3a obtained under the conditions of Example 12;
- Figure 2 is an optical purity HPLC chromatogram of the 3c compound obtained under the conditions of Example 17;
- Figure 3 is an optical purity HPLC chromatogram of the 3 l compound obtained under the conditions of Example 26.
- the reaction inner tube was charged into a high pressure reaction vessel. After replacing the gas in the autoclave with hydrogen, the initial hydrogen pressure was applied to 15 atm, and the reaction was stirred at room temperature for 24 hours. After the hydrogenation reaction is completed, hydrogen is released and the autoclave is opened.
- the reaction solution was filtered through a short short silica gel to remove the catalyst, and the reaction conversion was analyzed by nuclear magnetic resonance. After the product was derivatized into methyl ester, the optical purity was measured, and the results are shown in Table 1.
- B/S represents the ratio of the base to the substrate oxime-keto acid
- conv. represents the nuclear magnetic detection substrate conversion rate
- a substrate a-keto acid 2a (3 g, 20 mmol), potassium hydroxide (1.68 g, 30 mmol), a catalyst 1c (20 mg, 0.02 mmol) and n-butanol (50 mL) were added to a 200 mL hydrogenated inner tube.
- the reaction inner tube was charged into a high pressure reaction vessel. After replacing the gas in the autoclave with hydrogen, the initial hydrogen pressure was applied to 30 atm, and the reaction was stirred at room temperature for 10 hours. After the hydrogenation reaction is completed, hydrogen is released and the autoclave is opened. The reaction solution was filtered through a short short silica gel to remove the catalyst, and the conversion was 100% by nuclear magnetic analysis. After the product was derivatized to methyl ester, the optical purity was determined to be 84% ee.
- a substrate a-keto acid 2 m (4 g, 20 mmol), potassium t-butoxide (3.36 g, 30 mmol), catalyst 1b (20 mg, 0.02 mmol) and n-butanol (50 mL) were added to a 200 mL hydrogenated inner tube.
- the reaction inner tube was charged into a high pressure reaction vessel. After replacing the gas in the autoclave with hydrogen, the initial hydrogen pressure was applied to 15 atm, and the reaction was stirred at room temperature for 12 hours. After the hydrogenation reaction is completed, hydrogen is released and the autoclave is opened. The reaction solution was filtered through a short short silica gel to remove the catalyst, and the conversion was 100% by nuclear magnetic analysis. After the product was derivatized to methyl ester, the optical purity was determined to be 95% ee.
- a substrate a-keto acid 2o (2.6 g, 20 mmol), potassium t-butoxide (3.36 g, 30 mmol), catalyst 1b (40 mg, 0.04 mmol) and n-butanol (50 mL) were added to a 200 mL hydrogenated inner tube.
- the reaction inner tube was charged into a high pressure reaction vessel. After replacing the gas in the autoclave with hydrogen, the initial hydrogen pressure was applied to 15 atm, and the reaction was stirred at room temperature for 24 hours. After the hydrogenation reaction is completed, hydrogen is released and the autoclave is opened. The reaction solution was filtered through a short short silica gel to remove the catalyst, and the conversion was 100% by nuclear magnetic analysis. After the product was derivatized to benzyl ester, the optical purity was determined to be 85% ee.
