My research focuses on exploring novel catalytic system for the rapid and efficient construction of small molecules. Of great importance is that the methods are highly selective, which covers chemoselectivity, regioselectivity and enantioselectivity. I am particularly interested in exploring atom-economic, environment friendly and redox-neutral transformations enabling efficient and selective preparation of complex molecules and biologically privileged structural motifs. I am specifically involved in rhodium-catalyzed asymmetric C-H functionalization, novel cross-coupling reactions enabled by a dual TM/photoredox catalysis.
