  Synthesis of iPF2α-V: a new route

  摘要：

  We are reporting here on a new synthesis of iPF(2 alpha)-V, and we also disclose the first report on the synthesis of 12-epi-iPF(2 alpha)-V. The new total synthesis of iPF(2 alpha)-V reported here is designed to address metabolism and analytical issues. We have used this new route and also performed the total synthesis of 17,17,18,18-tetradeutero-iPF(2 alpha)-V. The availability of the deuterated analog of iPF(2 alpha)-V is the first step in our attempt to quantitate this isoprostane in biological fluids by GC and LC-MS. (C) 1999 Elsevier Science Ltd.

  systemic and/or specific biomarkers in various pathologies, and more especially, they were found to have their own biological properties. Produced in vivo as a non-separable mixture of isomers, their total synthesis is a keystone to answer biological questions. In this work, the total synthesis of three non-enzymatic oxylipins derived from docosahexaenoic acid (DHA) and docosapentanoic acid (DPAn-3) is

  stereocontrolled strategy toward the total synthesis of isoprostanes based on a bicyclic alpha,beta-epoxy ketone intermediate 6. Bicyclo[3.3.0]octene scaffold permitted stereodirection of reagents allowing stereoselective epoxidation, diastereoselective ketone reduction, and regioselective epoxide opening otherwise not accessible with a simple cyclopentene framework.

  New oxylipins from marine biomass. The first total synthesis of oxylipins, metabolites of γ-linolenic acid (GLA), dihomo-γ-linolenic acid (DGLA) and stearidonic acid (SDA) were accomplished. These metabolites are potential biomarkers of oxidative injury in marine biomass and could be involved in the defense mechanisms of these microorganisms.

• iPF2α-III metabolism. First total synthesis of 2,3-dinor iPF2α-III, a primary β-oxidation metabolite

  The total synthesis of a primary iPF(2 alpha)-III metabolite, namely dinor iPF(2 alpha)-III 8, is described. The successful synthesis was finally accomplished by generating the carboxylic acid group at the end of the synthesis so as to avoid formation of an alpha,beta -unsaturated carboxylic acid, which is prone to undergo side reactions (C) 2001 Elsevier Science Ltd.

  The first total synthesis of 17,18,19,20-d(4)-iPF(2 alpha)-III 32, a deuterated analog of iPF(2 alpha)-III is described. We have used this analog in some beta-oxidation studies with rat liver homogenates and have shown that 32 was metabolized to 17,18,19,20-tetradeutero2,3-dinor-iPF(2 alpha)-III 36 and 17,18,19,20-tetradeutero-2,3-dinor-5,6-dihydro-iPF(2 alpha)-III 37.
