Related Products of 3783-77-5, A common heterocyclic compound, 3783-77-5, name is 2-(3-Oxobutyl)isoindoline-1,3-dione, molecular formula is C12H11NO3, 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.
To a cold slurry of 2-(3-oxobutyl)isoindoline-l,3-dione (2.12 g, 9.76 mmol) in MeOH (25 mL) at 0 C was added bromine (1.006 mL, 19.52 mmol). The reaction mixture was allowed to slowly warm to room temperature overnight. The reaction mixture was initially quenched with 10 M aq H2SO4 (15 mL). Once the intermediate methyl ether was no longer visible by LCMS, the reaction mixture was diluted with additional water (20 mL). The solid was collected, rinsed with water and air dried on the filter to afford 2-(4-bromo-3-oxobutyl)isoindoline-l,3-dione (2.13 g, 7.19 mmol, 73.7% yield) as a white solid. LC/MS (weak M+H): 295.9; LC retention time: 2.148 min (analytical HPLC Method N); NMR (400 MHz, CDCh): delta ppm 7.86 (dd, J=5.5, 3.1 Hz, 2H), 7.73 (dd, J=5.5, 3.1 Hz, 2H), 4.02 (t, J=7.2 Hz, 2H), 3.93 (s, 2H), 3.13 (t, J=7.2 Hz, 2H).
The synthetic route of 3783-77-5 has been constantly updated, and we look forward to future research findings.
