Catalysis investigation for synthesis of 2-amino-4 h -pyran-3-carbonitriles containing propargyl group

Some different catalysts, such as organic and inorganic bases and basic ionic liquids  were used for synthesis of 2-amino-4H-pyran-3-carbonitriles containing  propargyl group. Efficient catalysts of these substances were estimated. The structures of the obtained compounds were confirmed by the modern spectroscopic methods (IR, 1H NMR, 13C NMR).
