Adding a certain compound to certain chemical reactions, such as: 769-42-6, 1,3-Dimethylbarbituric acid, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, category: pyrimidines, blongs to pyrimidines compound. category: pyrimidines
General procedure: To a solution of L-proline-melamine complex (3 mol%) in DMSO (2 mL) was added dimedone 0.025 mg (0.178 mmol), malononitrile (1 equiv) and benzaldehyde / isatin (1 equiv) and stirred at room temperature for 1-20 min. After completion of the reaction (monitored by TLC), ethyl acetate was added stirring and continued for another 5 min. The precipitate formed was filtered. Evaporation of solvent gave the crude product which was recrystallized using ethanol to give the pure compound.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,769-42-6, 1,3-Dimethylbarbituric acid, and friends who are interested can also refer to it.
