Research

Summary

The primary research interests of our group lie in the area of organic synthesis and methodology. We are particularly excited about probing new strategies for asymmetric catalysis using organocatalysts, transition metals and multi-component systems. One major criterion for selecting reactions for development will be their usefulness in providing valuable intermediates that will subsequently be used in the synthesis of biologically active compounds. We are further interested in the application of concepts from supramolecular chemistry to address current challenges in synthetic organic chemistry.
