Wang, Fu-Li published the artcileMechanism-based ligand design for copper-catalysed enantioconvergent C(sp3)-C(sp) cross-coupling of tertiary electrophiles with alkynes, COA of Formula: C9H10O3, the main research area is tertiary alkyl halide alkyne enantioconvergent radical cross coupling copper.
A general copper-catalyzed enantioconvergent C(sp3)-C(sp) cross-coupling of diverse racemic tertiary alkyl halides RX [R = 1-cyclohexyl-1-[(naphthalen-1-yl)carbamoyl]ethyl, 1-phenyl-1-(phenylcarbamoyl)propyl, 1-[(4-bromophenyl)carbamoyl]-1-phenylpropyl, etc.; X = Cl, Br] and I (R1 = Et, cyclopropyl, benzyl, etc.; R2 = Et, Ph, 3-bromophenyl, etc.) with terminal alkynes R3CCH (R3 = Ph, cyclohexen-1-yl, thiophen-2-yl, etc.) (87 examples) was demonstrated. Key to the success is the rational design of chiral anionic N,N,N-ligands, e.g., II (R4 = t-butylphenyl) tailor-made for the computationally predicted outer-sphere radical group transfer pathway. This protocol provides a practical platform for the construction of chiral C(sp3)-C(sp/sp2/sp3) bonds, allowing for expedient access to an array of synthetically challenging quaternary carbon building blocks of interest in organic synthesis and related areas.
