Abstract

A  method  for the synthesis of substituted 2,3-dioxo-1,2,3,4-tetrahydroquinoxalines by the reduction of substituted (o-nitrophenyl)glycines with subsequent oxidation of the 2-oxo-1,2,3,4-tetrahydroquinoxaline products has been developed. When tin(II) chloride was used as the reducing agent a chlorine atom was introduced ortho to the NHC(O) fragment of the heterocycle.
