Application of 317-20-4, 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. 317-20-4, name is 7-Fluoroisatin belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: In an oven dried reaction vial, ligand 1d (2.5 mol%) was dissolved in dry toluene (1 mL), and to the resulting solution Ti(OiPr)4(5 mol%) was added and the resulting solution was stirred for 2 hunder N2 at RT. To the above stirred solution (Ia)/isatin (0.17 mmol) was added and the stirring was further continued for another 30 min. After that, DMP (0.19 mmol) was added dropwise to the above solution over 30 min. While in the case of isatin derived ketimines, initially ligand 1d (2.5 mol%) was dissolved in dry toluene (1 mL), and Ti(OiPr)4(5 mol%) was added to it and the resulting solution was stirred for 2 h at RT. Then 4 A MS (20 mg)and isatin derived ketimines (IVa) were added under stirring condition. After 30 min, DPP (IIb) was added over a period of 30 min.The reaction was monitored by TLC using hexane/ethyl acetate(70/30) as eluent. After the completion of the reaction, the solvent was removed on a rotary evaporator, and the product was purified by flash column chromatography on a silica gel column(eluted with hexane/ethyl acetate = 70/30). The purified products were characterized by LCMS and NMR.
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-Fluoroisatin, other downstream synthetic routes, hurry up and to see.
