The Synthetic Utility of Amide and Amidine Derivatives Containing Polycarbonyl Moieties in the Synthesis of Β-Aminoenones
摘要:
The application of derivatives of the easily decomposing weak bases formamide, semi-carbazide, urea, or formamidine in the synthesis of beta-aminoenones is described. These compounds readily undergo transamination with strong bases, thus opening the way to various heterocyclic compounds.
3-b]quinoxalin-2(4H)-ones, potential bioactive compounds have been synthesized. Their preparation is based on the efficient, regiospecific condensation of o-phenylenediamine with pyrrolidine-2,3,5-trione (1) or its enaminone derivatives, respectively, affording two polymorphic forms of the latter in solid. The NMR spectral assignment of 3-benzoylpyrrolo[2,3-b]quinoxalin-2(4H)-ones confirms the presence
