Supramolecular double helical Cu(i) complexes for asymmetric cyclopropanation

Abstract

Chiral double-stranded helicates, formed between Cu(I) ion and C2-symmetric oligopyridines, were used for catalytic asymmetric cyclopropanation of alkenes; low catalyst loadings (0.2 mol%), high TONs (up to 404) and short reaction times (30–60 min) were achieved with [Cu2L2]OTf2 (L = chiral C2-symmetric terpyridine).
