  General Preparation and Controlled Cyclization of Acyclic Terpenoids

  摘要：

  [GRAPHICS]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 C-5 unit 5 and the chain-temination process utilizing the C5 unit 10 together with the chemoselective reductive desulfortylation. The polyprenols 12 were converted to compounds 3 containing two consecutive prenyl sulfone moieties at the tail end, which underwent the controlled electrophilic cyclization only at the carbon-carbon double bonds that were remote from the flat and rigid benzenesulfonyl groups.
