Dinuclear Ni2–Schiff base complex-catalyzed asymmetric 1,4-addition of β-keto esters to nitroethylene toward γ2,2-amino acid synthesis

Author affiliations

Abstract

A homodinuclear Ni2Schiff base 1 complex (1–10 mol%) promoted the catalytic asymmetric 1,4-addition reactions of β-keto esters and an N-Boc oxindole to nitroethylene, giving products in 98–75% ee.
