Heterocyclic Analogs of Thioflavones: Synthesis and NMR Spectroscopic Investigations

Heterocyclic Analogs of Thioflavones: Synthesis and NMR Spectroscopic Investigations

The synthesis of several hitherto unknown heterocyclic ring systems derived from thioflavone is described. Coupling of various o-haloheteroarenecarbonyl chlorides with phenylacetylene gives 1-(o-haloheteroaryl)-3-phenylprop-2-yn-1-ones, which were treated with NaSH in refluxing ethanol to yield the...
