Research Interests

• Asymmetric synthesis 
  Enzymes and Organocatalysts are two important pillars in asymmetric synthesis. We are currently working on development of novel asymmetric organocatalyst from cheap and readily available enantiopure substances such as monosaccharides and amino acids to study their catalytic role in various carbon-carbon bond forming reactions. Simultaneously, we are working on catalytic application of various lipases in (i) kinetic resolution of alcohols and amines, and (ii) multicomponent reaction guided by enzymatic promiscuity.
• Green synthetic methods
  Synthesis of complex molecular structures requires efficient chemical transformations. In our lab, we are working on development of new methods for synthesis of rapid assembly of complex molecules under solvent/catalyst-free conditions.
• 1,2,4-Trioxane Chemistry
  Given the success of artemisinin as one of the most effective drugs for the treatment of malaria and its recent success against diverse tumor cell lines, efforts to achieve simpler, yet efficient 1,2,4-trioxane (the essential pharmacophore of artemisinin) core is considered very important. We are currently engaged in development of asymmetric methods for synthesis of new 1,2,4-trioxanes to study their anticancer and antimalarial efficacies.
