SUMMARY:Boehringer-Ingelheim Seminar: Catalysis Innovation in Chemical Development: Effective Applications to BI Projects
DESCRIPTION:Abstract: Catalysis has become an indispensable\, frequently applied tool for devising convergent\, innovative\, asymmetric and economical synthesis of APIs in the pharmaceutical industry. BI-Catalysis group\, established in Ridgefield in 2008\, contributed to the development of novel processes in many BI projects at all stages of research and development through close collaboration with all BI sites. In addition to the screening function of commercially available ligands\, an innovative family of tunable BI-ligands was developed and emerged as privileged \nligands for applications to asymmetric catalysis. Screening capacity of catalytic reactions and selected examples from BI projects will be presented.

SUMMARY:Boehringer-Ingelheim Seminar: New Developments in Electrochemical Synthesis
DESCRIPTION:Abstract: Owing to its many distinct characteristics\, electrochemistry represents an attractive approach to discovering new reactions and meeting the prevailing trends in organic synthesis. In particular\, electrocatalysis—a process that integrates electrochemistry and small-molecule catalysis—has the potential to substantially improve the scope of synthetic electrochemistry and provide a wide range of useful transformations. Despite its attractive attributes and extensive applications in energy-related fields\, electrocatalysis has been used only sparingly in synthetic organic chemistry. Thus\, there exists a clear impetus for inventing new catalytic strategies to improve the scope of synthetic electrochemistry and provide new platforms for reaction discovery and synthetic innovations. Toward this end\, we developed a new catalytic approach that combines electrochemistry and redox-metal catalysis for the functionalization of alkenes to access a diverse array of vicinally functionalized structures. This talk details our design principle underpinning the development of electrocatalytic alkene difunctionalization and hydrofunctionalization with a particular emphasis on enantioselective electrocatalysis. In addition\, our recent forays into electroreductive chemistry will be discussed\, in which we harness the power of deeply reducing potentials to achieve previous challenging organic transformations.
