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

GENERAL METHOD OF STEREOSPECIFIC SYNTHESIS OF NATURAL POLYPRENOLS. SYNTHESIS OF BETULAPRENOL-6, -7, -8, AND -9

A stereoselective synthesis of (Z,Z,Z)-12-benzyloxy-1-chloro-2,6,10-trimethyldodeca-2,6,10-triene was achieved starting from (Z,Z)-farnesol.All the components of betulaprenols were synthesized using the C15 block 3 and its lower homologue (C10 block) as t
