  Fluorine-containing Heterocycles: X. Acetoacetamides in the Synthesis of Fluorine-containing Chromone

  摘要：

  Fluorine-containing chromone-3-carboxamides were synthesized by reaction of tetra(penta)fluorobenzoyl chlorides with acetoacetamides in dichloromethane in the presence of triethylamine. Nucleophilic substitution of fluorine atoms by amine rests in compounds synthesized was investigated.
