  A highly enantioselective Michael addition reaction of α,α-disubstituted aldehydes to β-nitrostyrenes has been developed. In the presence of rosin-based chiral primary amine-thiourea, γ-nitroaldehydes were afforded in excellent enantioselectivities (up to 99 % ee) with up to 99 % yield.

  Asymmetric Michael addition reactions of aldehydes to nitroolefins have been successfully initiated by a series of primary amine thiourea bifunctional catalysts, with high enantioselectivities (90–98% ee) and excellent yields (80–96%). The privileged quinine scaffold was found to be essential to the reaction efficiency and enantioselectivity.

  efficient protocol for the asymmetric catalytic Michael additions of α,α-disubstituted aldehydes to nitroolefins with a pyrrolidine-pyrazole is described. The desired products γ-nitrocarbonyl compounds possessing an all-carbon quaternary center, were obtained in good yields and with high levels of enantioselectivities under solvent-free reaction conditions, employing benzoic acid as an additive.

  The synthesis of calix[4]arene-based chiral bifunctional primary amine–thiourea catalysts has been described from p-tert-butylcalix[4]arene for the first time. The calix[4]arene-based catalysts were successfully applied to promote Michael addition of aldehydes with nitroalkenes affording preferentially the (R)- or (S)-adducts in high yields (up to 95%) and excellent enantioselectivities (up to 99%

  The oxytriazole catalyst "pyrrolidine-HOBt" developed for asymmetric Michael addition of cyclohexanone to nitroolefins is now evaluated for the asymmetric Michael addition of aldehydes to nitroolefins under similar reaction conditions. The results of this study indicate that, the oxytriazole catalyst "pyrrolidine-HOBt" is equally effective in promoting the Michael addition of aldehydes to nitroolefins on employing benzoic acid as an additive. The desired products, gamma-nitrocarbonyl compounds were obtained in good yields and high enantioselectivities. (C) 2017 Elsevier Ltd. All rights reserved.
