Asymmetric Büchner reactions are an effective methodology to bring about synthetic complexity from the common benzene motif, but effective, general catalytic methods are scarce. Here, the authors present divergent asymmetric arene dearomatization from ynamides using copper catalysis, wherein the catalytic cycle proceeds via a putative vinyl cation intermediate.
