My research interest mainly focus on the design and synthesis
of organocatalyst and study their catalytic application. We have carried out various reactions, such as: Michael reaction, aldol, Maniich reaction, a-amination and etc. We are interested in developing cascade reaction that to construct multifunctional group in the products with high chemical yield and stereoselectivities.

Techniques used in study

Reaction setup and monitor; TLC analysis; HPLC analysis;
Flash column chromatography; Separation and purification;
NMR spectroscopy; HRMS; Single crystal X-ray analysis.
