Adding a certain compound to certain chemical reactions, such as: 1127-59-9, name is 7-Methylindoline-2,3-dione, 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 1127-59-9, Quality Control of 7-Methylindoline-2,3-dione
General procedure: Isatin 1 (3 mmol), malononitrile (0.2 g, 3 mmol,), bicyclic CH-acid 2 (3 mmol) and sodium acetate (0.025 g, 0.3 mmol) in ‘solvent-free’ manner or with additive (‘on-solvent’ manner) were grinded with a pestle and mortar at ambient temperature for 15 minutes. After the reaction was finished, the mixture was air-dried. Then the crude solid was put on filter, rinsed with water (2 mL) and EtOH (2 mL), and then dried with a water pump to isolate the spiro-oxindole 3.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 7-Methylindoline-2,3-dione, other downstream synthetic routes, hurry up and to see.
