In the lab’s newest pre-print, we teamed up with the lab of Prof. Peng Liu at the University of Pittsburgh, to break ground on a new research direction aimed at unlocking copper as a general catalyst for nucleometalation to π-bonds. We discovered that under the right circumstances copper(II) is a potent π-Lewis acid that enables addition of various acidic OH and NH nucleophiles to unactivated alkynes, enabling stereodivergent access to enol esters, enolts, and enamides. Congrats to the project team: Juntao, Letian, and Shenghua from Scripps; and Thomas and Mithun from the University of Pittsburgh.
