Related Products of 883-44-3,Some common heterocyclic compound, 883-44-3, name is 2-(3-Hydroxypropyl)isoindoline-1,3-dione, molecular formula is C11H11NO3, 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.
Example 30 5-(1,3-Dioxo-1,3-dihydro-isoindol-2-ylmethyl)-2-(oxalyl-amino)thiophene-3-carboxylic acid; To a stirred mixture at 0 C. of 2-(3-hydroxy-propyl)-isoindole-1,3-dione (0.2 g, 0.97 mmol), 0.7 M sodium bromide (0.70 ml, 0.46 mmol), TEMPO (3.0 mg, 0.02 mmol) in dichloromethane (1 ml) was added dropwise a solution of bleach (2.1 ml, 4.9 mmol) and sodium hydrogen carbonate (117 mg, 1.4 mmol). The mixture was stirred at 0 C. for 2 hours after the addition was finished. The mixture was extracted with ethyl acetate (3*20 ml). The combined organic extracts were washed with 10% sodium thiosulphate (3*10 ml), brine (10 ml), dried (MgSO4), filtered and the solvent was evaporated in vacuo. The residue was washed with ethyl acetate (2*1 ml) affording after drying 161 mg (81%) of 3-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-propionaldehyde as a solid. 1H NMR (400 MHz, CDCl3) delta 9.82 (s, 1H), 7.85 (dd, 2H, J=5.6, 2.8 Hz), 7.73 (dd, 2H, J =5.6, 2.8 Hz), 4.04 (t, 2H, J=7.2 Hz), 2.89 (t, 2H, J=7.2 Hz).
The synthetic route of 883-44-3 has been constantly updated, and we look forward to future research findings.
