Huang, Shengying published the artcileAsymmetric sequential double Michael reactions of γ,δ-unsaturated β-ketoesters to nitroolefins catalyzed by Ni (II)-diamine complex, HPLC of Formula: 5153-73-1, the publication is Catalysis Communications (2017), 67-70, database is CAplus.
The asym. sequential double Michael reactions of γ,δ-unsaturated β-ketoesters and nitroolefins catalyzed by 2 mol% of readily prepared Ni(II)-bis[(R,R)-N,N’-dibenzylcyclohexane-1,2-diamine] complex and then with 1 equiv of tetramethylguanidine (TMG) for cyclization have been developed. The reaction gave the corresponding Michael adducts of multifunctional cyclohexenol derivatives with three chiral stereocenters in good yields, moderate diastereoselectivities, and high enantioselectivities under mild reaction conditions. Thus, e.g., γ,δ-unsaturated β-ketoester I + trans-β-nitrostyrene â?II (82%, dr = 5:1, 92% ee).
