A general preparation method of the all-(E)-polyprenols 12 has been developed from readily available geranyl sulfone by the chain-extension process utilizing the C5 unit 5 and the chain-termination process utilizing the C5 unit 10 to

Successive elongation by a C5 unit is possible when an allylic sulfone is couple with 4-bromo-3-methyl-2-butenyl phenyl sulfide (1). The thiosulfone compound formed was then oxidized to the corresponding disulfone, which, upon coupling with another equivalent of 1 and oxidation, produced the trisulfone 2, again elongated by a C5 unit (see scheme). This process, which can be repeated again, is the basis for a highly efficiently synthesis of carotenoids.
