Application of 81927-55-1, 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. 81927-55-1 name is Benzyl 2,2,2-trichloroacetimidate, 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.
To a solution of methyl (3R)-3-hydroxybutanoate (10 g) and benzyl 2,2,2-trichloroethanimidate (23.6 g) in CH2CI2 (300 mL) was added CF3SO3H (7.2 g) and the mixture was stirred at 25C for 12 h. The reaction mixture was concentrated under reduced pressure to remove CH2CI2. The residue was diluted with water (100 mL), extracted with four times with ethyl acetate (90 mL) and concentrated under reduced pressure. The residue was purified by column chromatography (5i02, petroleum ether / ethylacetate, 20:1 to 9:1) to give methyl (3R)-3-benzyloxybutanoate (10 g, 56.7%) as colorless oil. LCMS:209.1 (M÷Hi
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Benzyl 2,2,2-trichloroacetimidate, and friends who are interested can also refer to it.
