## Abstract No base is required for the Mg(II)‐catalyzed conjugate addition of nitromethane to α′‐hydroxy enones in the presence of molecular sieves. Good enantioselectivities are attained using 3 or 4β€…Γ… MS and about 10 mol % of Mg(OTf)~2~‐chiral bisoxazoline complexes. Elaboration of the adducts t
