Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 15469-97-3, name is 1-Trityl-1H-imidazole, A new synthetic method of this compound is introduced below., SDS of cas: 15469-97-3
To a THF solution (80 mL) of 1-tritylimidazol (3.10 g), n-butyllithium (1.6M hexane solution, 6.9 ml) was added dropwise in an argon atmosphere with ice-cooling. After stirring at the same temperature for 30 minutes, (R)-2-[(benzyloxy)methyl]oxirane (1.52 mL) was added thereto. After stirring for 1.5 hours with ice-cooling and stirring at room temperature for 1 hour, water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with water and brine, dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified by subjecting to silica gel chromatography (eluent; ethyl acetate:hexane = 1:1) to obtain the title compound (1.402 g) as a pale yellow oily product. 1H-NMR (CDCl3) delta: 2.06 (2H, dd, J = 2.8Hz, 18.0Hz), 3.08 (1H, dd, J = 5.4Hz, 9.8Hz), 3.21 (1H, dd, J = 5.4Hz, 9.8Hz), 3.55-3.7 (1H, m), 4.36 (2H, s), 6.73 (1H, d, J = 1.4Hz), 6.93 (1H, d, J = 1.4Hz), 7.0-7.4 (20H, m).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
