To provide a ligand having higher optical purity and high Syn-selectivity and a catalyst using the same. [Solution] The ligand is represented by the following formula (1). (Wherein R 1 and R 2 are hydrogen, an alkyl chain, a phenyl group (which may have a substituent) or a naphthyl group (which may have a substituent), and R 1 and R 2 R 1 and R 2 may be the same or different, and R 3 may be an alkyl group or a phenyl group (having a substituent). Or R 4 and R 5 may be hydrogen, fluorine, chlorine, bromine, iodine, nitro group, alkyl chain, alkoxy group, or phenyl group (substituted), or a naphthyl group (which may have a substituent). And R 4 and R 5 may be the same or different, and R 6 is hydrogen or an alkyl chain.) [Selection figure] None |
