experimental part, p. 1967 - 1974 (2009/02/07)
A practical and highly regio- and stereoselective synthesis of oligoprenols starting from commercially available geraniol is described. The convergent synthetic strategy features the iterative allyl-allyl coupling of monomers easily derived from geraniol that contain one reacting terminal functional group and the repetitive reductive elimination of the p-toluenesulfonyl (Ts) groups.

(1-13C)-, (2-13C)-, (3-13C)-, (3-13CH3)-, (4-13C)-, and (13CH3O)2-ubiquinone-10 and the corresponding (1-13C)-, (6-13C)-, (5-13C)-, (5-13CH3)-, (4-13C)-, and (13CH3O)2-ubiquinone-0 have been synthesised from simple labelled starting materials via a single reaction scheme.The ubiquinones have been characterised using mass spectrometry, 1H NMR and 13C NMR.The spectroscopic results indicate that, within experimental error, the syntheses have been accomplished without scrambling or dilution of label.All labelled ubiquinones have been synthesised on a decigram scale.

C5-chain growth in the structure of natural solanesol, isolated from tobacco, was realized by a C3 + C2 scheme.Decaprenol was separated into isomers with respect to the newly formed double bond by column chromatography on silica gel.The isomeric compositi
β,γ-dihydropolyprenyl alcohol derivatives and pharmaceutical composition containing a polyprenyl compound

A β,γ-dihydropolyprenyl alcohol derivative having the formula: STR1 wherein n is an integer of 5 to 7 and R is hydrogen, a lower alkyl group or an aliphatic or aromatic acyl group, is new and useful as a phylactic agent against human and animal infectious diseases. Other disclosed polyprenyl compounds are also useful as such agents.

Allylic p-tolyl sulphonates (5), (14), and (16) couple with allylic bromide (7) and geranyl bromide to produce regio- and stereo-chemically pure 1,5-diene systems.The coupling of all-trans-ω-bromogeranyl acetate (7) with geranyl p-tolyl sulphone (5) and higher isoprenologues (21), (24), and (27), followed by reductive elimination of p-tolylsulphonyl group, furnishes a stereoselective synthesis of all-trans-polyprenols (3), (23), (26), and decaprenol (1b).Solanesol (1a) was synthesised using trans-4-chloroprenyl acetate (29) instead of (7).

-
, (2008/06/13)
This invention relates to a hypertension treating agent comprising a polyprenyl alcohol or an ester thereof of the general formula: STR1 wherein n represents an integer of 7-10 and A represents a group of the general formula: STR2 in which a and b each represent hydrogen or they may form a bond, or STR3 in which R represents hydrogen or --COR', R' being a saturated or unsaturated aliphatic hydrocarbon group of 1-17 carbon atoms; cyclohexyl group; unsubstituted phenyl group or phenyl group substituted with a halogen atom or a lower alkoxy group; (halogen atom-substituted phenoxy)-lower alkyl group; or pyridyl group.
