Formal anti-Markovnikov Hydroamination of Terminal Aryl Alkynes with Pinacolborane and Hydroxylamines via Zr/Cu Sequential Catalysis
We have developed sequential Zr/Cu catalysis involving regioselective hydroboration and electrophilic amination for the formal anti-Markovnikov hydroamination of terminal aryl alkynes. The reaction system can provide a facile access to enamines from terminal acetylenes with high regioselectivity under mild conditions.
