Adding a certain compound to certain chemical reactions, such as: 317-20-4, name is 7-Fluoroisatin, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 317-20-4, HPLC of Formula: C8H4FNO2
General procedure: Indoles (0.20mmol), isatins (0.10mmol), and 60 wt%PWA/MCM-41 catalyst (0.0050 g) were stirred in THF(0.3mL) at room temperature for 2.5 h and monitored byTLC. The product were purified by column chromatographyon silica gel using petroleum ether/ethyl acetate (20 : 1, 10 : 1,5 : 1, 2 : 1, 1 : 1) as the eluent. All compounds (3a-3o) werecharacterized by 1H and 13C NMR (400MHz) spectral analysis.The catalyst was separated from the reaction mixture bycentrifugalization, dried at 473K for 4 h after washing withethanol, then continued to be reused for the next reaction.
