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. 7477-63-6, name is 7-Chloroisatin, A new synthetic method of this compound is introduced below., Product Details of 7477-63-6
General procedure: A mixture of isatins 1a-f (1 mmol), active cyanomethanes 2a-b (1 mmol), and enolizable ketones 3a-d (1 mmol) in ethanol (3 ml)was stirred at room temperature in the presence of HIL (Scheme 2).The reaction progress was monitored by thin-layer chromatography (TLC). After completion of the reaction, the reaction mixture was treated with ethanol to recover the insoluble catalyst by filtration.The filtrate was then concentrated under vacuum and the desired product was obtained. The structures of the products were confirmed by 1H NMR, IR spectroscopy, and supported by elemental analysis. The filtered catalyst was dried under vacuum for 2 h and was reused with a fresh charge of solvent and reactants for subsequent runs under the same reaction conditions to observe its catalytic efficiency.
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.
