The present invention provides a novel ligand represented by the following formula and a novel transition metal complex having the ligand, which shows superior enantioselectivity and catalytic efficiency, particularly high catalyst activity, in various asymmetric synthesis reactions.
A transition metal complex having, as a ligand, a compound represented by the formula
wherein R
4
is a hydrogen atom or a C
1-6
alkyl group optionally having substituent(s), and R
5
and R
6
are each a C
1-6
alkyl group optionally having substituent(s), or the formula
is a group represented by the formula
wherein ring B is a 3- to 8-membered ring optionally having substituent(s).
