Adding a certain compound to certain chemical reactions, such as: 31827-94-8, name is 2-Bromo-1-(4-iodophenyl)ethanone, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 31827-94-8, category: iodides-buliding-blocks
Into a mixture of 2-bromo-1-(4-iodophenyl)ethanone (5g, 15.4 mmol) and (S)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (3.48g, 16.1 mmol) in acetonitrile (40 mL) was added diisopropylethylamine (2.4 mL, 17 mmol). The resulting mixture was stirred at rt for 3 hours before being partitioned between EtOAc and aqueous NaHCO3. The organic phase was separated, dried (Na2SO4) and concentrated to afford a brown oil. It was purified by flash column chromatography (silica, hexane-EtOAc) to give the desired product as light yellow oil (6.0 g, 86%). ESIMS m/z=481.94 [M+Na]+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Bromo-1-(4-iodophenyl)ethanone, and friends who are interested can also refer to it.
