Title

FE(NO3)3 AS AN EFFICIENT CATALYST FOR REGIO- AND STEREO-CONTROLLED RING EXPANSION OF 1,2-DIAROYL-3-ARYLAZIRIDINES

Pages

  979-984

Abstract

 Several 1,2-diaroyl-3-arylAZIRIDINEs were previously prepared conveniently and used in the preparation of 5-benzoyl-2,4-diaryl OXAZOLINEs in the presence of NaI. In this work, synthesis of some trans-4-benzoyl-2,5-diaryl OXAZOLINEs by a REGIO- AND STEREO-CONTROLLED reaction in the presence of Iron (III) nitrate at room temperature is reported. A plausible mechanism has been proposed for RING EXPANSION of N-acyl AZIRIDINEs to OXAZOLINEs.
