Compound and Asymmetric Synthesis Reaction

An asymmetric synthesis reaction, comprising:

• allowing a compound represented by the following General Formula (4) and a compound represented by the following General Formula (5) to react with each other in the presence of a chiral silver complex obtained from a silver compound and a compound represented by the following General Formula (A) to thereby obtain a compound represented by the following General Formula (6):
• where Ra each independently represents a hydrogen atom, an alkyl group, an alkoxy group, an alkenyl group, an aryl group, an arylalkyl group, an arylalkenyl group, a non-aromatic heterocyclic ring, or an aromatic heterocyclic ring, m is an integer of 1 or 2;
• when m is 2, two Ra may be bonded together to form a ring structure;
• and Ar represents an aryl group which may have a substituent,
• where in General Formulas (4) to (6), R11 represents a hydrogen atom or a substituent, R12 represents a methyl group or an ethyl group, and n is an integer of 1 to 3.
