Syntheses and preliminary pharmacological evaluation of the two epimers of the 5-F2t-isoprostane
摘要:
The total synthesis of the 5-F-2t-isoprostane I and its 5-epimer 2 from diacetone-D-glucose is described. We report preliminary data on the vascular properties of these compounds. (C) 2001 Elsevier Science Ltd. All rights reserved.

A library of eight 5-F-2-isoprostanes was prepared through a ring-opening metathesis/cross-metathesis protocol between functionalized bicyclo[3.2.0]heptenes, ethylene, and alpha,beta-unsaturated ketones. This sequence provided racemic enones in a regio- and stereoselective fashion that could be converted to enantiomerically enriched allylic alcohols through a catalyst-controlled asymmetric reduction. Completion of the sidechains, followed by global deprotection, resulted in a stereodivergent route to eight enantiomerically enriched 5-F-2 isoprostanes. Overall, the synthesis of this library of known and anticipated lipid oxidation metabolites was achieved in 10 steps from commercially available 4-hydroxy-2-cyclopentenone.
