ChemInform Abstract: Synthesis of 3-Aminooxindoles via Acid-Promoted Cyclization of α-Imino-N-arylamides and α-Azido-N-arylamides.

α-Imino-N-arylamides [e.g. (I)] undergoes Friedel-Crafts cyclization to give 3-aminooxindoles [e.g. (II)] in high yields and the products can also be obtained from α-bromo-N-arylamides [e.g. (X)] in a one-pot fashion. [ABSTRACT FROM AUTHOR]
