Conjugate addition reactions of Thiochromone with Organometallic reagents provide a rapid entry into Thiochromanone and Thioflavanone, an important class of bioactive organosulfur compounds. Excellent yields of 1,4-adducts – thiochromanone and thioflavanone can be isolated (up to 92%). The large library of thiochromanone and thioflavanones can be quickly synthesized by using commercially available or easily prepared organometallic reagents. These thioflavanones and thiochromanones are useful precursors for many pharmaceuticals, such as 1,5-benzothiazepine, a versatile pharmacophore in drug discovery. Thioflavanones and thiochromanones could be converted into useful sulfoxides and sulfones in high yields.
