Application of 2058-72-2, 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. 2058-72-2, name is 5-Bromo-1-methylindoline-2,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: At the first, a mixture containing (10% mol) aimin base ligand and transition metal salts (10% mol) was prepared in 10 ml dichloromethan. Then a mixture of isatin derivatives (1 mmol) and (S)-proline (1.1 mmol), in 10 mL ethanol was added to mixture. After completion of the reaction (monitored by TLC), the reaction mixture was extracted with dichloromethane (15 mL). The combined organic layer dried over anhydrous MgSO4. The organic layer was concentrated in vacuum to furnish the products, which were recrystallized from ethanol.
The synthetic route of 5-Bromo-1-methylindoline-2,3-dione has been constantly updated, and we look forward to future research findings.
