Conjugate addition reactions of Thiochromone with Organometallic reagents such as alkyllithium catalyzed by Copper(I) salts are investigated in the synthesis of Thiochromanone, an important class of organosulfur compounds with rich bioactivities. Excellent yields of 1,4-adducts – thiochromanones can be isolated (up to 90%). The use of commercially available or easily prepared organometallic reagents will expedite the synthesis of a large library of thiochromanones for further synthetic applications and biological studies. Thiochromanones are key intermediates for bioactive products such as sulfoxides and sulfones.Not Submitted

Role: I developed and efficient synthetic approaches to thiochromanone via organocopper catalyzed conjugate addition reaction. I showed that this reaction works for a broad range of substrate with both electon-withdrawing and electron-donating groups. Thiochromanone is an important class of organosulfur compounds with rich bioactivities. I also demonstrated that these sulfur compounds are useful intermediates for sulfoxides and sulfones.
