Synthetic Route of 2058-72-2, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 2058-72-2 as follows.
General procedure: To a solution of ligand 1(11mol %) in ethanol (2 ml) was added coppersalt (10 % mol), After 5 hours the color of the solution changed from blue-green to purple. Then,dipolarophile (0.20 mmol) has been added andstirred about 30 min. Next, a mixture of isatin derivatives (0.20 mmol) and (S)-proline (0.21 mmol), in 3 ml ethanol/dichloromethane (5/1) was added to reaction mixture.After completion of the reaction (monitored by TLC), reaction was diluted withdiethyl ether and filtered through a pad of silica gel. The organic layer wasconcentrated in vacuum to furnish the products, which were recrystallized fromethanol.
According to the analysis of related databases, 2058-72-2, the application of this compound in the production field has become more and more popular.
