Electric Literature of 15469-97-3, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 15469-97-3 name is 1-Trityl-1H-imidazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
(i) (2R)-1-(benzyloxy)-3-(1-trityl-1H-imidazol-2-yl)-2-propanol In an argon atmosphere, n-butyllithium (1.6 M solution in hexane, 6.9 ml) was added drop by drop to a solution of 1-tritylimidazole (3.10 g) in THF (80 ml) under ice cooling. After stirring at the same temperature for 30 minutes, (R)-2-[(benzyloxy)methyl]oxirane (1.52 ml) was added. After stirring under ice cooling for 1.5 hours and at room temperature for 1 hour, water was added and the reaction mixture was extracted with ethyl acetate. The extract was washed with water and saline and dried over magnesium sulfate, after which it was concentrated under reduced pressure. The residue was purified by silica gel chromatography (eluent: ethyl acetate-hexane 1:1) to yield the titled compound (1.402 g) as a pale-yellow oily substance. 1H-NMR (CDCl3) delta: 2.06 (2H, dd, J=2.8 Hz, 18.0 Hz) 3.08 (1H, dd, J=5.4 Hz, 9.8 Hz), 3.21 (1H, dd, J=5.4 Hz, 9.8 Hz), 3.55-3.7 (1H, m), 4.36 (2H, s), 6.73 (1H, d, J=1.4 Hz), 6.93 (1H, d, J=1.4 Hz), 7.0-7.4 (20H, m).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Trityl-1H-imidazole, and friends who are interested can also refer to it.
