Professor Chang's group studies new organic reactions and mechanisms with transition metal catalysis. Research topics in our group have ranged in the development of new useful synthetic methodologies based on transition metal chemistry, synthesis of biologically important products, organic catalysis, chirality amplification and molecular mechanics based on molecular assembly. Research goals include catalytic C-H bond activation for the C-C bond formation, development of useful catalytic organic transformations for organic synthesis, highly efficient asymmetric induction based on organic chiral catalysts, elucidation of origin of chirality amplification, magnetic impact on chirality, and development of organic molecular mechanics based on molecular assembly, crystal engineering, and metallodendri Research goals include catalytic C-H bond activation for the C-C bond formation, development of useful catalytic organic transformations for organic synthesis, highly efficient asymmetric induction based on organic chiral catalysts, elucidation of origin of chirality amplification, magnetic impact on chirality, and development of organic molecular mechanics based on molecular assembly, crystal engineering, and metallodendrimers.
