Disclosed are: a ligand for an asymmetric synthesis catalyst; and a process for producing an α-alkenyl cyclic compound using the ligand. Specifically disclosed are: a ligand for an asymmetric synthesis catalyst, which is represented by any one of formulae (1) to (4) [wherein R
1
represents —Cl or —Br; R
2
represents —CH
3
or —CF
3
; and R
3
represents —CH
2
—CH═CH
2
or —H]; and a process for producing an α-alkenyl cyclic compound using the ligand.
