Total Synthesis of the Eight Diastereomers of the Syn-Anti-Syn Phytoprostanes F1 Types I and II
摘要:
Syntheses of the eight enantiomerically pure diastereomers of the syn-anti-syn phytoprostanes F-1 types I and II are described starting from D- and L-glucose. Key steps include Wittig coupling, Horner Wadsworth Emmons (HWE) reactions, and enantioselective reduction of alpha,beta-unsaturated ketones.

Radical cyclization of acyclic 1-substituted-2,4-dihydroxylated 5-hexenyl radicals produced functionalized cyclopentane derivatives. These cyclopentanic precursors after different protection/deprotection reactions followed by Wittig and Horner–Wadsworth–Emmons coupling reactions led to the main urinary tetranor metabolites of 15-F2t-isoprostane (8-epi-PGF2α).
