2973-17-3, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.2973-17-3, name is 1-Allyl-1H-pyrrole-2,5-dione. An updated downstream synthesis route of 2973-17-3 as follows.

General procedure: A mixture of maleimide 3 (0.24 mmol), anthrone 2 (0.2 mmol), and the catalyst (20 mol %) in 1,2-dichloroethane (0.6 mL) at -10 C was stirred for 12 h (monitored by TLC). After evaporation under reduced pressure, the residue was purified through column chromatography on silica gel (petroleum ether/ethyl acetate=3/1) to yield pure products.

A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article. If you are also interested in other aspects of 1-Allyl-1H-pyrrole-2,5-dione, you can also browse my other articles.

General procedure: (All the reactions were performed on 50mg scale of aldehyde.) A reaction mixture containing K2CO3 (80mol%), NHC precatalyst A (15mol%), maleimide 2 (1.5 equiv) and aldehyde 1 (1.0 equiv) in THF (2mL) under argon atmosphere was stirred at 50C for 30min to 2h. When the reaction was complete, the crude reaction mixture was allowed to attain room temperature, followed by filtration of the reaction mixture through a bed of celite. The residue was washed with ethyl acetate (5mL x 3) and the combined filtrate was evaporated under reduced pressure. The crude reaction mixture was purified by column chromatography on silica gel using solvent gradient of petroleum ether:ethyl acetate to furnish the desired products 4-13, 15-21 in 10-90% yield., 2973-17-3
