Chiral, self-supported, polytopic imidazoline-pyridine ligands were designed and synthesized for use in Cu catalysis. The tripodal imidazoline-pyridine L6-Cu(BF 4 ) 2 complex catalyzed the asymmetric p-(tert-butyl)benzoylation of mesohydrobenzoin to give the adduct in up to 85 % ee. After com-
A catalyst system generated from Cu(BF4)2 and new chiral imidazoline—pyridine ligands is used to promote the title reactions of meso‐diols (III) to afford the corresponding adducts with enantioselectivities up to 85%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
