Synthesis of Oxazolidin‐2‐ones <i>via</i> a Copper(I)‐Catalyzed Tandem Decarboxylative/Carboxylative Cyclization of a Propiolic Acid, a Primary Amine and an Aldehyde

Abstract

Abstract A facile approach to polysubstituted oxazolidin‐2‐ones is presented via a copper(I)‐catalyzed tandem decarboxylative/carboxylative cyclization of a propiolic acid, a primary amine and an aldehyde (PA 2 ‐coulpling). This new multicomponent coupling constitutes an efficient methodology to provide the corresponding oxazolidin‐2‐ones in good yields.
