  Efficient Synthesis of Nitroflavones by Cyclodehydrogenation of 2′-Hydroxychalcones and by the Baker-Venkataraman Method

  摘要：

  Several nitroflavone derivatives were synthesized by cyclodehydrogenation of 2'-hydroxychalcones and by the Baker-Venkataraman approach, starting from 2'-hydroxyacetophenones and benzoic acid derivatives. Nitroflavones synthesised by the first synthetic approach were obtained in better global yields than those obtained by the later method. The structures of all new compounds were elucidated by microanalyses, 1D and 2D NMR, IR, and mass spectroscopic measurements.
