Novel One‐Pot Synthesis of Aziridines Containing Sydnone Moiety

Abstract

A novel series of 1,1a‐dihydro‐1‐aryl‐2‐(3‐aryl‐sydnone‐4‐yl)‐azirino[1,2‐a] quinoxalines were prepared in a one‐pot reaction of 2,3‐dibromo‐1‐(3‐arylsydnone‐4‐yl‐)‐3‐arylpropan‐1‐one with o‐phenylenediamine employing triethylamine in ethanol. The new compounds were well characterized by IR,¹H NMR, mass spectra, and C,H,N analysis.

Keywords:

• aziridines
• dibromochalcones
• quinoxalines
• sydnone derivatives
