Organo-synthesis and catalysis

Research in this area is the development of novel greener methods for organic synthesis. In this regard, a number of methods such as domino reactions, multicomponent reactions, transition metal catalysed reactions, organocatalysis and catalysis using efficient materials have extensively been explored. The research mainly focus on homogeneous catalysis of C-H activation transformed into C-C bonds.

Researcher also aims in devicing a novel and modular methodology to develop a range of DNA-based catalyst in which catalytic unit in the form of transition metal complex could be covalently anchored into the chiral DNA. Next step would be the application of those chiral catalyst for various asymmetric organic transformation.
