Electric Literature of 17702-83-9, These common heterocyclic compound, 17702-83-9, name is 2-(8-Bromooctyl)isoindoline-1,3-dione, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
200 mg (0.484 mmol) of 112 was dissolved in DMF (8 mL). 466 mg (1.43 mmol) of CS2CO3 and 819 mg (2.42 mmol) N-(8-bromooctyl)phthalimide were added and the mixture was sonicated for 1.5 h. Solvent was removed under reduced pressure and the resulting residue was purified by preparatory TLC (CH2Cl2:MeOH:AcOH, 15: 1 :0.5) to give 120 mg (34percent) of 113d. lH NMR (500 MHz, CDC13) delta 8.29 (s, 1H), 7.84 (dd, J= 5.5, 3.1 Hz, 2H), 7.70 (dd, J= 5.5, 3.1 Hz, 2H), 7.28 (s, 1H), 6.87 (s, 1H), 6.29 (br s, 2H), 5.96 (s, 2H), 4.18 (t, J= 7.5 Hz, 2H), 3.67 (t, J= 7.3 Hz, 2H), 1.62- 1.77 (m, 4H), 1.25- 1.36 (m, 8H); MS (ESI) m/z 671.3 [M+H]+.
Statistics shows that 2-(8-Bromooctyl)isoindoline-1,3-dione is playing an increasingly important role. we look forward to future research findings about 17702-83-9.
