Synthetic Route of 5332-26-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5332-26-3, name is 2-(Bromomethyl)isoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
Bromomethylphtalimide (85 mg, 0.35 mmol), sodium iodide (53 mg, 0.56 mmol) and cesium carbonate (177 mg, 0.54 mmol) were added to a solution of DO3AtBu under argon atmosphere (172 mg, 0.33 mmol) in freshly distilled acetonitrile (5 mL). The suspension was heated to reflux for 24 h, before being filtered at room temperature. The yellow filtrate was evaporated under reduced pressure and 10 mL chloroform was added in order to precipitate residual inorganic impurities. Evaporation of the solvent and addition of 20 mL of ether led to precipitation of a yellow powder corresponding to the sodium adduct C35H55N5O8.NaI.H2O (191 mg, 67% yield). 1H NMR (CDCl3) d: 7.82-7.71 (m, 4H), 4.66 (s, 2H), 3.27-2,34 (broad signals overlapping, 22H), 1.48-1,40 (two signals overlapping, 27H); 13C NMR (CDCl3) d: 173.91, 173.30, 169.70, 134.58, 131.69, 123.59, 83.03, 82.73, 57.62, 56.48, 55.69, 53.55, 51.77, 51.15, 48.34, 28.06, 27.88. Anal. Calcd for C35H55N5O8.NaI.H2O: C, 49.94; H, 6.83; N, 8.32. Found: C, 50.13; H, 6.67; N, 8.49.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(Bromomethyl)isoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.
