In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2058-74-4, name is 1-Methylisatin belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 2058-74-4
General procedure: A mixture of isatin (1 mmol), malononitrile (1 mmol) and dimedone (1 mmol) was stirred at room temperature in the presence of SnO2 nanoparticles and 2 mL of EtOH. The reaction progress was monitored by TLC (n-hexane/ethyl acetate, 2:1 ratio). After that, the resulted mixture (containing the solid product and nano catalyst) was dissolvedin acetone and filtered for separation of the catalyst. Finally, the product 5a was obtained after evaporation of acetone and for further purification recrystallized from EtOH.
The synthetic route of 2058-74-4 has been constantly updated, and we look forward to future research findings.
