Synthesis and Characterization of New Pyrano[2,3-<i>c</i>]pyrazole Derivatives as 3-Hydroxyflavone Analogues

In this paper, an efficient synthetic route from pyrazole-chalcones to novel 6-aryl-5-hydroxy-2-phenylpyrano[2,3-<i>c</i>]pyrazol-4(2<i>H</i>)-ones as 3-hydroxyflavone analogues is described. The methylation of 5-hydroxy-2,6-phenylpyrano[2,3-<i>c</i>]pyrazol-4(2<i>H</i>)-one with methyl iodide in th...
