Research Interests

Research in our laboratory focuses on organic chemistry, catalysis, and medicinal chemistry. We are particularly interested in exploring new chemical processes that utilize earth-abundant and biocompatible catalysts to construct value-added molecules in a rapid and selective manner.

Catalytic processes for rapid formation of multiple chemical bonds

Our research efforts are devoted to the revealing of new catalytic reactivity that involves one-step selective formation of multiple carbon-carbon and carbon-heteroatom bonds. Such reactivity would allow for effective construction of complex skeletons and polyfunctionalized molecules. Specifically, we are interested in new multicomponent cyclization systems that utilize simple and noncyclic starting materials for constructing heterocyclic and heteropolycyclic structures. Mechanistic study-guided catalyst design is used as a powerful tool to investigate new pathways for solving some of the long standing problems.

Selective functionalization of unsaturated hydrocarbons

Further development of new transformations of unsaturated hydrocarbons will always bring exciting opportunities for synthetic chemistry and other applicable areas such as fine chemical, pharmaceutical, and material sciences. In our lab, we are exploring new types of catalytic activation of heterocyclic small rings for selective functionalization of unactivated alkenes and related unsaturated hydrocarbons. Through the development of both transition and main group element-based catalysts, together with ligand design, these catalytic systems are expected to be able to effectively control and switch chemoselectivity and stereoselectivity. The catalytic processes developed in our group are applied for the syntheses of synthetically and pharmaceutically important molecules, agrochemicals, and functional materials. 

Postions Open

Research positions in our group are available to both graduate and undergraduate students.  Enthusiastic and motivated students who are interested in synthetic chemistry and catalysis are encouraged to contact Dr. Cui for further details.
