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.
