ABSTRACT:
Compounds represented by the following general formula (1a) or (1b).A complex comprising a center metal of rhodium and a compound represented by the following general formula (1a) or (1b) as a ligand. A catalyst for optically active beta-substituted carbonyl compound synthesis and catalyst for asymmetric 1, 2 addition reaction being composed of the complex. A method of production of an optically active beta-aryl compound from an alpha, beta-unsaturated compound and an aryl-boronic acid derivative and method of production of an optically active aryl alcohol compound from an aldehyde compound and aryl boronic acid derivatives using the catalyst. A complex comprising a center metal of palladium and a compound represented by the following general formula (1a) or (1b) as a ligand. A catalyst for asymmetric allylic substitution reaction being composed of the complex. A method of production of an optically active dialkyl (1,3-disubstituted propeny)malonate compound from a 1,3-disubstituted ally acetate compound and a dialkyl malonate and method of production of an optically active allylamine compound from a 1,3-disubstituted ally acetate compound and an amine compound. The compounds have not only the versatility of being usable in the synthesis of wide-ranging optically active aryl compounds but also the selectivity and reactivity permitting synthesis with high yield within a short period of time under industrially advantageous mild conditions.
