Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 169037-23-4, name is 5-(Trifluoromethoxy)indoline-2,3-dione, A new synthetic method of this compound is introduced below., 169037-23-4
General procedure: A mixture of beta-nitrostyrenes, isatin and tyrosine (1:1:1) was stirredunder heating at 100 C for 1 h in [bmim]Br (200 mg). After the reaction was completed, 10 mL of ethyl acetate was added to the reaction mixture and stirred for 15 min. The organic layer was separated, washed with water, and dried. The cycloadduct was further purified using hexane: ethyl acetate (3:2 v/v) as eluent employing column chromatography technique. After extraction of the cycloadduct, [bmim]Br wasdried under vacuum at 80 C for 2 h to exclude any water trapped from moisture and reused for subsequent runs.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
