  Studies on the Chemical Behavior of the Novel 6,8-Dibromo-7-hydroxychromone-3-carboxaldehyde towards Some Carbon Nucleophilic Reagents

  摘要：

  A novel 6,8-dibromo-7-hydroxychromone-3-carboxaldehyde (4) was prepared by the Vilsemier-Haack formylation of 3,5-dibromo-2,4-dihydroxy acetophenone (3). The chemical reactivity of carboxaldehyde 4 was studied towards some carbon nucleophiles as cyclic and acyclic active methylene nucleophiles and also 1,3-C,N- and 1,3-C,C-binucleophiles as a route to achieve ring transformation to produce a variety of heterocyclic systems. Structures of the newly synthesized products have been deduced on the basis of elemental analysis and spectral data.
