| Abstract | ||
| In this work,pyranopyrazoles derivatives have been synthesized Underconventional and microwave conditions.The compounds(1-5) were prepared by heating hydrazine derivatives with ethyl acetoacetate and then repeated the reaction by microwave technique. While the Sciffe bases (8-11)were synthesized by the condensation of compounds (6,7) with aromatic aldehydes and then repeated the reaction by microwave technique. Treatment of compound (2) with naphthylisocyanate or ethylisothiocyanate to give derivatives (12-13)and then repeated the reaction by microwave technique. The structure of the synthesized compounds were deduced by using some spectroscopic methods,UV –Visible ,FT-IR and NMR. | ||
