Research Interests

Stereoselective catalysis has revolutionized the art of chemical synthesis and tremendous progress has been made in this area over the last few decades. Despite these advances, many existing protocols suffer from poor applicability and often rely on catalyst systems that contain increasingly expensive noble metals. The high cost and limited availability of these metals makes it compelling to search for more economical and sustainable alternatives.
The key objective of our program is to develop sustainable and enabling catalytic solutions that address critical and unresolved problems in chemical synthesis. Our research approach will leverage creative, direct and unprecedented disconnections of complex target molecules to fuel our efforts in devising practical stereoselective methods that utilize abundant, biocompatible and inexpensive catalysts. Insights gained from mechanistic studies will aid us in designing new catalyst systems that promote transformations to facilitate economically and environmentally viable preparation of important compounds for the chemical, pharmaceutical and polymer industries.
Current topics of interest include: (a) development of catalytic transformations involving organohalides for rapid assembly of bioactive natural products and pharmaceuticals, (b) design and preparation of novel fluorinated building blocks for medicinal and polymeric material applications and (c) discovery of new reactivity patterns and transformations for engaging radicals in enantioselective catalysis. We cordially welcome collaborations in all areas of research including total synthesis, computational studies, chemical biology and materials science.
