ChemInform Abstract: Polycarbonyl Heterocycles. Part 3. Synthesis of 2,3‐Furanodione Derivatives by Ring Transformations of Thiazolidine‐4,5‐dione Derivatives.

Abstract

Treatment of thiazolidinediones (I) with an equimolar amoünt of the amines (II) leads to the salts (III) (IR, 1H NMR and mass spectra).
