A series of Ni(II) complexes with novel chiral ligands derived from (1R,2R)‐1,2‐diphenylethane‐1,2‐diamine was synthesized. The catalytic activity of these complexes in the asymmetric Michael reaction is demonstrated. Asymmetric addition of diethyl malonate to ω‐nitrostyrene and 1‐nitropent‐1‐ene in the presence of these complexes leads to the enantiomerically enriched diethyl (S)‐2‐(2‐nitro‐1‐phenylethyl)malonate (up to 96 % ee) and (R)‐diethyl 2‐(1‐nitropenthan‐2‐yl)malonate (up to 91 % ee). (4R)‐4‐Propylpyrrolidin‐2‐one, the key intermediate of antiepileptic drug brivaracetam, was obtained from the corresponding nitroester.
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.
