New synthesis of 3-bromoflavones via bromination of 1-(2-hydroxyphenyl)-3-arylpropane-1,3-dione by CuBr2, and conversion into 3-aminoflavones
A new synthesis of 3-bromoflavones from 1-(2-hydroxyphenyl)-3-arylpropane-1,3-dione using CuBr2 is described. The usefulness of 3-bromoflavone as a precursor of 3-aminoflavone is also described.
