Application of 39755-95-8, The chemical industry reduces the impact on the environment during synthesis 39755-95-8, name is 5-Methoxyisatin, I believe this compound will play a more active role in future production and life.
General procedure: A mixture of malononitrile (1 mmol), isatin (1 mmol), dicarbonyl (1 mmol), PEGOSO3H(0.1 mmol), and water (2 mL) was stirred under reflux for the appropriate time (shown in Tables 3, 4). After completion of the reaction, the reaction mixture was filtered and the residue was washed with ethanol. The crude solid product was recrystallized from EtOH to afforded the pure products in high purity and yield.Assignment of the structures of the products was based on their 1H NMR, 13C NMR,and IR spectra.
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, 5-Methoxyisatin, other downstream synthetic routes, hurry up and to see.
