Abstract

An efficient synthetic method for 2-ethoxy-2-oxophosphorindolines, benzo-γ-phospholactams, has been successfully achieved through the copper-catalyzed intramolecular aromatic C–H insertion of diazophosphonamidates with up to 97% yield. The current method has advantages of mild and clean conditions, and an inexpensive catalyst.
