Adding a certain compound to certain chemical reactions, such as: 2058-74-4, name is 1-Methylisatin, 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 2058-74-4, Recommanded Product: 1-Methylisatin
General procedure: To a mixture of isatin (1 equiv.) and indole (1 or 2 equiv.) in water (3 mL), CuWO4 (10 mol%) was added and the mixture was stirred at room temperature for 2 h or heated at 60 C for 2 h. After completion of the reaction (monitoring by TLC), the mixture was cooled (in the case of bis-indolyl-2-oxindoles) and extracted with EtOAc (2×10 mL). The organic layers were washed with brine, dried using sodium sulfate. Evaporation of the solvent gave the desired product which was purified by silica gel column chromatography. Elution of the column with PE:EtOAc gave the desired products (5 or 6).
