Research Interest

Development of privileged medicinal scaffolds is the key step in drug discovery program. We are involved in a cutting-edge C-H activation technology for the synthesis of heterocycles and other medicinally relevant molecules. This technology is particularly important for the late-stage modification of functional molecules to impose desired properties. Furthermore, multiple C-H activation in a cascade manner will enable us to achieve molecular diversity as well as complexity from simple, readily available, inexpensive starting materials. This approach will generate library of multifunctional molecules for Alzheimer’s Disease, breast cancer research. Simultaneously, we are developing green chemical transformations from biomass and other renewable recourses to generate value added products such as fine and bulk chemicals with a particular interest in the activation and utilization of CO2 for value added products. Combining these two technologies we are developing cost effective and green chemical processes for the off-patent drugs, active pharmaceutical ingredients (APIs) and agrochemicals.
