| Description |
1187-1191
Alumina-supported iodobenzene diacetate [PhI(OAc)<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub>] is a highly efficient reagent for the oxidative cyclization of <i style="">N</i>-arylidene-N′–[3-(4-fluorophenyl)-[1,8]naphthyridin-2-yl]-hydrazines <b style="">7 </b>to<b style=""> </b>1-aryl-4-[4-fluoro phenyl]-1,2,4-triazolo[4,3-<i style="">a</i>][1,8]naphthyridines <b style="">8 </b>in solvent-free conditions under microwave irradiation. The products are obtained in good yields and excellent purities. The structural assignments of compounds <b style="">3-8</b> were based on their spectral (IR, <sup>1</sup>H NMR and MS) and analytical data. |
