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. 2058-74-4
General procedure: A solution of N-methylisatin (81 mg, 0.5 mmol), phenylacethylene (77 mg, 0.75 mmol), CuI (19 mg, 0.1 mmol), and Cs2CO3 (245 mg, 0.75 mmol) in CH3CN (1.0 mL) was stirred at room temperature for 18 h. After aqueous extractive work up and column chromatographic purification process (CH2Cl2/EtOAc, 15:1) 1a was obtained as a pale yellow soild, 81 mg (61%). Other compounds were prepared similarly, and the spectroscopic data of unknown compounds 1b, 1d, and 1e are as follows.
The synthetic route of 2058-74-4 has been constantly updated, and we look forward to future research findings.
