Enantioselective nickel-catalyzed Mizoroki–Heck cyclizations of amide electrophiles†
Abstract
Amide cross-couplings that rely on C–N bond activation by transition metal catalysts have emerged as valuable synthetic tools. Despite numerous discoveries in this field, no catalytic asymmetric variants have been disclosed to date. Herein, we demonstrate the first such transformation, which is the Mizoroki–Heck cyclization of amide substrates using asymmetric nickel catalysis. This proof-of-concept study provides an entryway to complex enantioenriched polycyclic scaffolds and advances the field of amide C–N bond activation chemistry.
