Reference of 2058-74-4,The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research.
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.
