Recent Progress on the Synthesis of (Aza)indoles through Oxidative Alkyne Annulation Reactions

Abstract

The oxidative [3+2] cycloaddition of alkynes with arylamines is a powerful method for the synthesis of (aza)indoles because it employs unfunctionalized and easily available materials. Herein, recent progress in the synthesis of (aza)indoles through transition metal-catalyzed oxidative [3+2] cycloaddition is highlighted.
