Aziridine Synthesis and Ring Opening

The cost-effective synthesis of nitrogen-containing small molecules remains an important challenge in organic chemistry. The value of carbon-nitrogen bonds can be highlighted by simply observing their prevalence in commercial pharmaceuticals, where 80-90% of the top 200 medications contain at least one carbon-nitrogen bond. Aziridines, three-membered nitrogen-containing rings, are useful intermediates for the synthesis of small molecules. Our group has become interested in developing new methodologies for the formation and stereoselective ring opening of aziridines. Direct access to enantioenriched tryptamine, phenethylamine, diamine, and amino alcohol derivatives is possible.

Small Molecules for the Treatment of Human Disease

Chiral organic small molecules represent a large class of pharmaceutical active ingredients. Many of our methods projects produce chiral synthons that possess unique structural features. Our group maintains an inventory of compounds that are submitted for enzyme binding assays or whole cell assays to determine if interesting biological activity exists. Specifically, several hundred compounds have been submitted to the Psycoactive Drug Screening Program (PDSP), Lilly's Open Innovation Drug Development (OIDD) program, and the Community for Open Antimicrobial Drug Discovery (CO-ADD).
