Research Interests

Present Research

Asymmetric Organic Synthesis. Research in the group is focussed toward the synthesis of natural and synthetic bioactive molecules using catalalytic asymmetric protocols employing novel methodologies, reagents and reactions. Sulfoxides, sulfilimines (nitrogen counterpart of sulfoxides) are advantageously employed as intramolecular nucleophiles for the vicinal functionalization of alkenes to prepare chiral synthons. Recently α-chloro sulfides have been utilized as reactive intermediates in C-C bond forming reactions as a route to 1,4-diols, 1,4-amino alcohols etc.

Past Research

As a research scholar I was involved in the synthesis of a complex heptacyclic natural product morellin. Model studies were carried out to synthesize the tricyclic core and xanthene residues. Cyclohexadienes prepared by metal-ammonia reuction of aromatic substrates were utilized for this research.

Projects Involved

Received funding from DST for five G. A. P thus far. Involved as a team member in projects sponsored by GSK and ArQule.
