652-39-1, 4-Fluoroisobenzofuran-1,3-dione is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
652-39-1, A mixture of the above 4-fluoroisobenzofuran-1,3-dione (40 g, crude) and L-glutamine (35 g, 239 mmol) in dry DMF (200 mL) was stirred at 90 for 8 h. The solvent was removed under reduced pressure. The residue was re-dissolved in 4N HCl (200 mL) and stirred for additional 8 h. The resulting precipitation was collected by filtration, washed with water, and dried to afford 5-amino-2-(4-fluoro-1,3-dioxoisoindolin-2-yl)-5-oxopentanoic acid (37 g, crude) as an off-white solid. LC-MS: 295.2 [MH]+.1H NMR (400 MHz, CDCl3): delta 2.16-2.20 (m.2H), 2.31-2.43 (m, 2H), 4.79-4.83 (m, 1H), 6.79 (br, 1H), 7.26(br, 1H), 7.77-7.85 (m, 2H), 7.98-8.03 (m, 1H), 13.32(br, 1H).
The synthetic route of 652-39-1 has been constantly updated, and we look forward to future research findings.
