Process for preparing optically active nitro compounds and cyano compounds

摘要

ÄProblemÜ 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. <??>ÄSolutionÜ 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.
