The invention relates to polyprenyl compounds of the general formula
wherein
represents a trans-isoprene unit,
represents a cis-isoprene unit, n is an integer of 11-19, Z' is -CH20H or a functional precursor thereof, and either one of R' and R2 is a hydrogen atom and the other is -S(O)mR3 in which m is an integer of 0 (zero), 1 or 2 and R3 is a phenyl, naphthyl, pyridyl or thiazolinyl group which may optionally have one or more substituents selected from lower alkyl groups and halogen atoms. These polyprenyl compounds can be synthesized by reacting a compound of the general formula
with a compound of the general formula
with the aid of an anionizing agent.
(either one of A and X being a halogen atom and the other being -S(O)mR3)
These polyprenyl compounds can be converted into mammalian dolichols or precursors thereof by reductive elimination of the -S(O)mR3 group.
