Synthetic Route of 17702-83-9, 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. 17702-83-9, name is 2-(8-Bromooctyl)isoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
a) Preparation of 8-(cis/trans-2,6-dimethyl)morpholinyloctyl phthalimide 8-Bromooctylphthalimide (9 g; 26.60 mmoles) and 2,6-dimethyl morpholine (cis-trans isomers mix) (9.8 ml; 79.5 mmoles) were dissolved in anhydrous acetonitrile (50 ml). The mixture was allowed to stir at room temperature for 18 hours approx. The reaction was discontinued by solvent evaporation under reduced pressure. The collected residue was purified by chromatography on silica gel (CH2 Cl2 /MeOH 95:5). The first product isolated (Rf =0.7) is a light yellow oil (A trans) (2.04 g), the second (Rf =0.4) is a yellow oil (B cis) (3.4 g). Total yield 54.8percent. Analysis: calcd.: C,70.93; H,8.66; N,7.52. Compound A (trans isomer) found: C,71.14; H,8.58; N,7.59. Compound B (cis isomer) found: C,71.07; H,8.53; N,7.65.
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-(8-Bromooctyl)isoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.
