Electric Literature of 3001-72-7, 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 3001-72-7 as follows.
General procedure: The reaction mixture of azlactones 1a-p (0.2mmol) and DBN (2b, 0.03mL, 0.22mmol) was stirred at room temperature for the appropriate time according to Scheme 2. After completion of the reaction as monitored by TLC (eluent: petroleum ether/ethyl acetate, 4:1), the mixture was extracted with ethyl acetate (3×5mL). The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. Purification by silica gel column chromatography (10-35% ethyl acetate in petroleum ether) afforded the products 3ab-pb.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3001-72-7, its application will become more common.
