  DBN (1,5-diazabicyclo(4.3.0)non-5-ene) with activated olefins, i.e., 2-arylidenemalononitriles and 2-cyano-3-aryl acrylates, to afford tricyclic 2-pyridones and pyridin-2(1H)-imines, respectively. The mechanism has been proposed based on DFT calculations. In the reaction, the cyclic amidines serve as C,N-bisnucleophiles for the cyclization, while the olefins play a dual role by acting as both reactants

  The first catalytic enantioselective decarboxylative propargylation/hydroamination reaction of ethynyl benzoxazinanones with malononitriles enabled by organo/copper cooperative catalysis was established. Various 3-indolin-malononitrile derivatives, displaying a high tolerance for functional groups, could be obtained in good yields with high levels of enantioselectivity (up to 85% yield, 96:4 er).

• The Synthesis of Some Derivatives Based on the 4-Benzyl-1H-pyrazole-3,5-diamine Core

  The three-step synthesis of 4-benzyl-1H-pyrazole-3,5-diamines 2 from commercially available aldehydes 3 is given. The Knoevenagel condensation was utilized to assemble the initial carbon framework, resulting in the benzylidenemalononitriles 4 which were directly transformed by the reduction of the electron deficient C=C bond to benzylmalononitriles 5. Subsequent cycloaddition of hydrazine with 5 afforded the desired pyrazoles 2. Due to the high similarity with 4-arylazo-1H-pyrazole-3,5-diamines, the biological activities of the 4-benzyl-1H-pyrazole-3,5-diamines 2 were evaluated while focusing on the inhibition of cyclin-dependent kinases (CDKs), but no significant results were obtained.
