of bioactive molecules [1–5]. A possible approach to preparation of these compounds is asymmetric addition of β-oxophosphonates to nitroalkenes [6]. Earlier, we have shown that complexes of nickel [7], cobalt, and manganese [8] with chiral diamines are efficient catalysts for enantioselective addition of 1,3dicarbonyl compounds to nitroalkenes. This reaction has been used as a key step in synthesis
