devised that allows access to rearrangement products in good to excellent isolated yields. Furthermore, we have developed a two-component, one-pot sequence using a microwave-assisted oxadiazole condensation/Boulton-Katritzkyrearrangement to deliver 3-(acylamino)-1H-indazoles from simple esters and 2-amino-N-hydroxy-benzamidine Boulton-Katritzkyrearrangement - indazole - microwave-assisted - oxadiazole

Copper promoted C-S and C-N cross-coupling Reactions:The synthesis of 2-(N-Aryolamino)benzothiazoles and 2-(N-Aryolamino)benzimidazoles
The synthesis of 2-(N-aryolamino)benzothiazoles and 2-(N-aryolamino)benzimidazoles has been accomplished in the presence of copper catalyst. These reactions involve C-S and C-N cross-coupling reaction. All electron donating and withdrawing substituent's readily underwent the reaction to give target products in good to excellent yield. In addition, the reaction also gave target product in high yield
