[Problem] The problem of the invention is to prepare nitro compounds and cyano compounds in high efficiency and high stereoselectivity by a simple and practical Michael reaction.
[Solution] A process for preparing optically active nitro compounds and cyano compounds representedbythechemical formula (C) using a metal complex, which is obtained by reaction of an optically active nitrogen-containing compound and a periodic table group VIII metal complex, in the asymmetric Michael reaction of a compound represented by the chemical formula (A) and a compound represented by the chemical formula (B) according to the claim 1.
