A method for producing an optically active 2,3-dihydrofarnesal of formula (1) is disclosed. The method includes subjecting β-farnesene f formula (2) to amination in the presence of a lithium salt of an amine to obtain (2E)-farnesyl allylamine of general formula (3); subjecting the (2E)-farnesyl allylamine to asymmetric isomerization to obtain an optically active farnesyl enamine of general formula (4); and subjecting the optically active farnesyl enamine to solvolysis:
