Alkylation and 1, 3-Dipolar Cycloaddition of 6-Styryl-4, 5-dihydro-2H-pyridazin-3-one: Synthesis of Novel N-Substituted Pyridazinones and Triazolo[4, 3-b]pyridazinones
Abstract : Some new N -substituted pyridazinones and triazolo[4, 3-b]pyridazinones were synthesized, respectively, by simple alkylation and 1, 3-dipolar cycloaddition of pyridazin-3-one with nitrile imines. The regioselectivity of the reactions was ascertained by 1 H, 13 C NMR spectroscopy and X-ray diffraction of the synthesized compounds.
