| Rezumat | ||||||
4-(Dimethylamino)pyridine was found to be an efficient homogenous catalyst for one-pot multi-component reactions between hydrazine monohydrate, ethyl cyanoacetate, ketone, and malononitrile for the synthesis of 1,6-diamino-2-oxo-1,2,3,4-tetrahydropyridine-3,5-dicarbonitrile derivatives using ultrasonication at room temperature in ethanol solution within 35-50 min with yields of over 90%. This procedure offers various remarkable features such as short reaction times, clean reaction condition, excellent yields, and easy work-up methods. |
