this report, we reported a copper-catalyzed asymmetric atom
transfer radical addition (ATRA) reaction, which remains a great challenge
since the discovery of racemic ATRA in the 1940s. This enantioselective
radical chlorination of acrylamides was developed, where three reagents,
including Togni-I and TMSCl, PhICF3Cl, and CX3SO2Cl, were employed as the radical sources and chlorine
source, affording a series of chlorinated carbon-centered quaternary
compounds in good yields with excellent enantioselectivity. Notably,
the well-designed bulky chiral ligand plays a key role in the successful
enantioselective radical chlorination process.
