Total synthesis of 5(S),15(S)-dihydroxy-6,13-trans-8,15-cis-eicosatetraenoic acid (5,15-diHETE) and 8(S),15(S)-dihydroxy-5,11-cis-9,13-trans-eicosatetraenoic acid (8,15-DiHETE), two novel metabolites of arachidonic acid
enantioselective total synthesis of the (9S, 18R)-diastereomer of this macrocyclic polyene lactam. Key elements of the synthesis are i) the synthesis of the required chiral building blocks by employing readily accessible building blocks from the chiral pool, that is, (S)-malic acid and (R)-hydroxyisobutyric acid, ii) assembly of a linear polyene precursor by means of Wittig and Horner olefination reactions as

Cyclamenol A is a naturally occurring inhibitor of leukocyte adhesion to endothelial cells. The (9S,18R) diastereomer of cyclamenol A seco acid was synthesized by employing Sonogashira couplings and olefination reactions as the key steps. (C) 2000 Elsevier Science Ltd. Air rights reserved.

日期:——
A facile synthetic route to (-)-Geissman-Waiss lactone, a key intermediate of necine bases, was established by employing ring closing metathesis (RCM), followed by intramolecular Michael reaction of the resulting a,p-unsaturated lactone, as the key steps.
