• Stereoselective Synthesis of Exocyclic Tetrasubstituted Vinyl Halides via Ru-Catalyzed Halotropic Cycloisomerization of 1,6-Haloenynes
  作者：Barry M. Trost、Christopher A. Kalnmals

  DOI：10.1021/acs.orglett.7b00879

  日期：2017.5.5

  Herein, a ruthenium-catalyzed cycloisomerization that transforms 1,6-haloenynes into 5-membered carbo- and heterocycles that bear exocyclic, stereodefined, tetrasubstituted vinyl halides is reported. The reaction is insensitive to air and water, tolerates a variety of functional groups, and proceeds with good to excellent stereoselectivity and yield.

  Three new PUFA‐metabolites, namely 18‐F3t‐isoprostane (IsoP) from eicosapentaenoic acid (EPA), 20‐F4t‐neuroprostane (NeuroP) from docosahexaenoic acid (DHA) and 20‐F3t‐NeuroP from docosapentaenoic acid (DPAn‐3) were synthesized by two complementary synthetic strategies. The first one relied on a racemic approach to 18(RS )‐18‐F3t‐IsoP using an oxidative radical anion cyclization as a key step, whereas

  氧化应激（OS）是体内导致自由基过度产生的过程，它会触发多不饱和脂肪酸（PUFA）过氧化，从而导致外消旋非酶氧化的代谢产物的形成。作为OS的潜在生物标志物，它们的体内定量非常受关注。然而，由于大量异构体代谢产物是平行形成的，因此如果没有一级标准品，它们的定量仍然很难进行。三个新的PUFA代谢物，即18-F 3吨-isoprostane（ISOP）从二十碳五烯酸（EPA），20-F 4吨从十二碳六烯酸-neuroprostane（NeuroP）（DHA）和20-F 3吨-NeuroP从二十二碳五烯酸（DPA n-3）是通过两种互补的合成策略合成的。第一个方法是采用外消旋方法对18（RS）-18 F 3t -IsoP进行氧化反应，该方法以氧化自由基阴离子环化为关键步骤，而第二个方法则是通过酶法将二环[3.3.0]辛烯中间体进行消旋环辛二烯进行不对称合成。合成的代谢物应用于靶向脂质组学，以证明商业营养食品食用油中脂质的过氧化作用。

  Two novel methyl‐substituted arachidonic acid derivatives were prepared in an enantioselective manner from commercially available chiral building blocks, and were found to be excellent templates for the development of (13S)‐methyl‐substituted anandamide analogues. One of the compounds synthesized, namely, (13S,5Z,8Z,11Z,14Z)‐13‐methyl‐eicosa‐5,8,11,14‐tetraenoic acid N‐(2‐hydroxyethyl)amide, is an

• Novel, potent THC/anandamide (hybrid) analogs

  The structure-activity relationship (SAR) of the end pentyl chain in anandamide (AEA) has been established to be very similar to that of Delta(9)-tetrahydrocannabinol (Delta(9)-THC). In order to broaden our understanding of the structural similarities between AEA and THC, hybrid structures 1-3 were designed. In these hybrids the aromatic ring of THC-DMH was linked to the AEA moiety through an ether linkage with the oxygen of the phenol of THC. Hybrid 1 (O-2220) was found to have very high binding affinity to CB1 receptors (K-i = 8.5 nM), and it is interesting to note that the orientation of the side chain with respect to the oxygen in the phenol is the same as in THCs. To further explore the SAR in this series the terminal carbon of the side chain was modified by adding different substituents. Several such analogs were synthesized and tested for their CB1 and CB2 binding affinities and in vivo activity (tetrad tests). The details of the synthesis and the biological activity of these compounds are described. (c) 2007 Elsevier Ltd. All rights reserved.
