One-Pot Synthesis of 2-(Dicyanomethylene)-1,2-dihydropyridine Derivatives. -A simple protocol for the synthesis of the title species by a domino process between 1,3-dicarbonyl compounds and malononitrile dimers in the presence of NaNO 2 as base is presented. -(BARDASOV*, I. N.; ALEKSEEVA, A. U.; MIHAILOV, D. L.; ERSHOV, O. V.; NASAKIN, O. E.; TAFEENKO, V. A.; Tetrahedron Lett. 55 (2014) 16, 2730-2733, http://dx.

Heterocyclization of Arylmethylidene Derivatives of Malononitrile Dimer: Synthesis of 4-Amino-6-aryl-2-halopyridine-3,5-dicarbonitriles. -Highly functionalized pyridines are prepared via nucleophilic addition of arylmethylidene derivatives of malononitrile dimer halides to hydrogen (I) followed by cyclization and aromatization under the action of SeO2 or Br2 as the oxidizing agent. -(BARDASOV*, I. N.; MIHAILOV, D. L.; ALEKSEEVA, A. U.; ERSHOV, O. V.; NASAKIN, O. E.; Tetrahedron Lett. 54 (2013) 1, 21-22, http://dx.
