Synthesis of 1,3-thioxoketones from salicylaldehyde

A method for the synthesis of monothiodibenzoylmethanes was developed. The method involves a reaction of potassium thioacetate with 1-(2-hydroxyphenyl)-3- phenylpropynone prepared from salicylaldehyde.

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. Copyright

Synthesis of halogenated/nitrated flavone derivatives and evaluation of their affinity for the central benzodiazepine receptor

A series of halogenated/nitrated flavone compounds were synthesized. Some of the products were found to be potent central benzodiazepine receptor (BDZ-R) ligands. The structure-activity relationships (SAR) analysis of the new synthetic compounds, together with that of others already described, indicates that substitutions at position 6 or 6 and 3' in the flavone nucleus are the only ones that give rise to high affinity BDZ-R ligands.
