IBX-promoted domino reaction of α-hydroxy amides: a facile one-pot synthesis of isatins

Abstract

A novel and temperature-controlled oxidation of α-hydroxy amides in the presence of IBX is described. The divergent one-pot synthesis of isatins and α-formyl amides was achieved in good to excellent yields under metal-free conditions. And these two mild methods can tolerate a variety of functional groups, and are operationally simple.
