Synthesis and NMR characterization of (Z, Z, Z, Z, E, E,ω)- heptaprenol

We describe a practical, multigram synthesis of (2Z,6Z,10Z,14Z,18E,22E)-3, 7,11,15,19,23,27-heptamethyl-2,6,10,14,18,22,26-octacosaheptaen-1-ol [(Z 4,E2,ω)-heptaprenol, 4] using the nerol-derived sulfone 8 as the key intermediate. Su

Total Synthesis of (+)-9,10-syn- and (+)-9,10-anti-Copalol via Epoxy Trienylsilane Cyclizations

Total syntheses of (+)-9,10-syn-copalol (5), the pyrophosphate ester of which is a likely intermediate in the biosynthesis of 9,10-syn diterpenes, and its 9,10-anti isomer 39 are reported.Lithiation of (-)-(6R)-6,7-epoxygeranyl p-tolylsulfone (-)-19 or (+

Regio- and Stereo-selective Oxidation of gem-Dimethyl Olefins via -Sigmatropic Rearrangement of Allyl Amine Oxides

Highly regio- and stereo-selective oxidation sequences are described for the efficient conversion of the gem-dimethyl olefin terminus of acyclic terpenes to terminal trans-allylic alcohols and trans α,β-unsaturated aldehydes.

FACILE FUNCTIONALIZATION OF THE ISOPROPYLIDENE TERMINUS OF ACYCLIC MONOTERPENES BY WAY OF BENZENESULFENYL CHLORIDE ADDITION

Highly site- and regioselective terminal functionalizations of acyclic monoterpenes 1 via benzenesulfenyl chloride addition followed by hydrolysis assisted by silica gel, dehydrochlorination under neutral or weakly basic condition, or dehydrochlorination by strongly basic treatment respectively providing β-hydroxy sulfides 3, terminal methallylic sulfides 4, or vinylsulfides 5 are developed.Conversion of 4 to terminal trans-allylic alcohols 10 via sulfoxides 9 by the Evans procedure is also described.

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).
