Abstract

Abstract A straightforward and practical synthesis of N′, N′-disubstituted N-aryl-1, 2- ethylenediamines, starting from anilines, via N-aryloxazolidin-2-ones is described. A decarboxylative ring-opening reaction of N-aryloxazolidin-2-ones, using aliphatic secondary amines, is the key step in this procedure. A one-pot synthesis of N-aryloxazolidin-2-ones is also described. N′, N′-Disubstituted N-aryl-1, 2-ethylenediamines are a useful building ...
