A process for the preparation of a polyprenol represented by formula (1): where Y and Z individually represent a hydrogen atom or are coupled together to form a carbon-carbon bond; R represents a hydrogen atom or a protective group for a hydroxyl group, and n is 0 or an integer not less than 1, by reacting an organic complex of an alkali metal with a compound represented by formula (2): where either V represents a halogen atom, while W and X are coupled together to form a carbon-carbon bond, or X represents a halogen atom, while V and W are coupled together to form a carbon-carbon bond; A represents a protective group for a hydroxyl group, and Y, Z and n are as defined above.
