An efficient procedure between imidazo[1,2-a]pyrimidine-2-carbaldehyde, malononitrile, enolizable C-H activated acidic compounds, and sodium carbonate is described for the synthesis of potential biologically active, novel imidazo[1,2-a]pyrimidine-based pyran analogs through one pot, multicomponent reactions at room temperature. This method provided mild reaction conditions, simple purification without column chromatography, and moderate to good yields for the construction of imidazo[1,2-a]pyrimidine-based pyran derivatives. The structures of target compounds were established with different spectroscopic analyses.
