With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.118949-61-4,2,6-Bis((S)-4-isopropyl-4,5-dihydrooxazol-2-yl)pyridine,as a common compound, the synthetic route is as follows.

General procedure: (R)-LiPr (50mg, 0.17mmol) was dissolved in acetonitrile (15cm3). Zinc(II) tetrafluoroborate hydrate (20mg, 0.083mmol) was then added and the solution stirred at room temperature for one hour. A large excess of diethyl ether was added and the resultant precipitate was isolated by vacuum filtration leaving a white powder. Single crystals suitable for X-ray diffraction analysis were grown by vapour diffusion of diethyl ether into a concentrated solution of the product in acetonitrile. Yield: 0.054g, 78%.

118949-61-4, As the paragraph descriping shows that 118949-61-4 is playing an increasingly important role.

To a solution of [Ru(p-cymene)Cl2]2 (306 mg, 0.5 mmol) and pybox-ip (301 mg, 1.0 mmol) in MeOH (7.0 mL) wasadded a solution of disodium pyridine-2,6-dicarboxylate (1.0 mmol) in MeOH-H2O (2:1 v/v, 15 mL) under argonatmosphere. The mixture was stirred at 60 oC for 1 h. The product was extracted with CH2Cl2 (40 mL). The combinedorganic layers were concentrated and the residue was purified by silica gel column chromatography withCH2Cl2MeOH (50:1 v/v) to give A* as a dark greenish-violet solid (444.0 mg, 0.78 mmol) in 78% yield.

A 20 mL two-necked round-bottomed flask was charged with 69.2 mg (0.23 mmol, MW: 301) of pybox- ip, 87.6mg(0.46 mmol, MW: 190.45) of CuI and 5.0 mL of anhydrous CH2Cl2. A slow stream of nitrogen was passed throughthe system, and the solution was stirred well at room temperature for 24 h by means of magnetic stirring bar. Theexcess CuI was filtered off and the solvent of the filtrate was removed under reduced pressure and a yellow solid wasformed. After drying in vacuum at room temperature, the yield of F was 76.0% (85.4 mg). The structure of thiscatalyst was not confirmed., 118949-61-4
