Synthesis and characterization of novel biheterocyclic compounds from 3-alkoxy-1H-pyrazole-4-carbaldehydes via multicomponent reactions

Several series of novel biheterocyclic compounds have been synthesized starting from 3-alkoxy-1H-pyrazole-4-carbaldehydes and employing different types of multicomponent reactions. The structures of the obtained 4-(pyrazol-4-yl)pyrano[2,3-c]pyrazole, 4-(pyrazol-4-yl)pyrazolo[4′,3′:5,6]pyrano[2,3-b]quinoline, 4-(pyrazol-4-yl)pyridine, and 4-[(pyrazol-4-yl)methylidene]-1,2-oxazole derivatives were thoroughly characterized and confirmed using detailed nuclear magnetic resonance spectroscopy (NMR), high-resolution mass spectrometry (HRMS), infrared spectroscopy (IR), and X-ray analysis.
