We recently reported the design, synthesis, and novel reactivity of a family of 6-membered annulated chiral N-heterocyclic carbene (6-NHC) copper(I) complexes.1-6 Chiral 6-NHC ligand structure was inspired by OLED materials. The steric properties and electronic properties of chiral 6-NHC ligand were evaluated by the X-ray and IR analysis of 6-NHC-Rh complexes.1,4 This family of copper(I) complexes exhibited high enantioselectivities for β-borylation reactions and stereoconvergent allylic substitutions.2-4 It also gave high diastereoselectivities in catalyst controlled double allylic substitutions for the synthesis of 1,2-polyols4 and high regioselectivities in hydroborations of propargylic substrates.5,6 Finally, we demonstrated practical applications of flow reaction for the continuous synthesis using NHC-copper complexes in β-borylation reactions.7 Further details will be provided in the presentation.
