The NiCo2O4@Ni(BDC) metal-organicframeworks as a suitable and green catalyst have been developed for the one-pot synthesis of 2,4-diamino-6-arylpyrimidine-5-carbonitrile derivatives. The multi-component reactions of aldehydes, malononitrile and guanidine hydrochloride were efficiently catalyzed using a novel metal-organicframework under reflux conditions. Simple procedures, high yields, short reaction

Magnesium oxide (MgO) effectively catalyzes the three-component reaction of aldehydes, amidine systems, and malononitrile or ethyl cyanoacetate to form 4-amino-5-pyrimidine carbonitrile and pyrimidinone derivatives, respectively. The salient features of this method include high conversions, short reaction times, cleaner reaction profiles, and the use of inexpensive and readily available catalyst.

AbstractAn efficient one‐pot multicomponent synthesis of 2,4‐diamino‐5‐pyrimidinecarbonitrile derivatives has been achieved in excellent yields by the condensation of aromatic aldehydes, malononitrile, and guanidine using ionic liquid under controlled microwave irradiation (100 W) at 60°C. This green approach offers a number of advantages in terms of methodology, high‐product yield, short reaction time, mild reaction conditions, and easy workup. J. Heterocyclic Chem., (2011).
