Description :
2 hydroxy substituted calcone (I a-d) was dissolved in DMSO and mercuric acetate was added to it. The reaction mixture was refluxed for 2-3 hours and then diluted with water. The solid separated was crystallized from rectified sprit to give coumarone 3-one i.e. aurone (II a-d). Substituted aurone further refluxed with thiourea in ethanolic KOH for 3 hours gives substituted thiohydantoin. The structural elucidation of compound was done on the basis of analytical and spectral data.
