- 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.

- Stereoselective Synthesis of Solanesol and all-trans-Decaprenol
-
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).
