<P>PROBLEM TO BE SOLVED: To provide a novel industrially useful identifying agent for optical isomers and to provide a novel catalytic element for asymmetric synthetic reactions and an asymmetric synthetic reagent and a catalyst for the asymmetric synthetic reactions using the element. <P>SOLUTION: An optically active 1,1'-bi-2-naphthyl-dimer derivative is represented by formula (1) or formula (2), where As denote each a methoxymethyl group. The optically active 1,1'-bi-2-naphthol-dimer derivative is represented by formula (3) or formula (4). Various kinds of asymmetric reactions are carried out by using the compound represented by formula (3) or formula (4) as the identifying agent for optically active compounds or the catalytic element for the asymmetric synthetic reactions. <P>COPYRIGHT: (C)2004,JPO |
