Thiochromone undergo conjugate addition reactions with arylcuprates to afford 2-substituted thio- flavanones, providing an efficient synthetic approach to privileged sulfur-containing structural motifs and valuable precursor for many pharmaceuticals. Excellent yields of substituted thioflavanones are achieved with lithium diarylcuprates, lithium arylcyanocuprates and Grignard reagents with copper catalysis. This method provides a rapid entry to a variety of thioflavanones in excellent yields (up to 92%). The use of commercially available or easily prepared organometallic reagents will expedite the synthesis of a large library of thioflavanones for further synthetic applications and biological studies.Not Submitted

Role: In this research, I conducted conjugate addition reactions to arylcuprates to thiochromone. This is the first example of organocuprates addition to thiochromone. This apporach provides a rapid entry into privileged sulfur-containing structural motifs and valuable precursor for many pharmaceuticals.
