  摘要：

  描述了环状prodigiosin衍生物4的第一个全合成，它构成了开发免疫抑制剂的潜在先导化合物。该方法的关键步骤包括相当不稳定的吡咯硼酸衍生物17与富电子吡咯基三氟甲磺酸酯15的钯催化Suzuki交叉偶联反应，然后是所得二烯的闭环易位反应（RCM），形成大环靶分子环。通过使用茚基钌配合物21作为预催化剂可以最好地实现这种转化。如此形成的产物18.HCl的X射线数据表明，互变异构体形式B正确描述了该生物碱杂芳族链段内的电子分布，

• Synthesis of Borondipyrromethene (BODIPY)-Labeled Sphingosine Derivatives by Cross-metathesis Reaction
  作者：Carsten Peters、Andreas Billich、Michael Ghobrial、Klemens Högenauer、Thomas Ullrich、Peter Nussbaumer

  DOI：10.1021/jo062347b

  日期：2007.3.1

  A new efficient and flexible synthesis of fluorescently labeled sphingosine derivatives from commercially available Garner aldehyde (8) is described. For this, appropriate alkenylated borondipyrromethene (BODIPY) dyes were synthesized and used for the first time in a cross-metathesis reaction, the key step of the approach. The labeled sphingosines with appropriate chain length were accepted as substrates by sphingosine kinases (SPHKs), yielding the corresponding phosphorylated products. One of these derivatives (11d) was identified as the first reported selective substrate for SPHK-1.
• Synthesis and Characterization of BODIPY-α-Tocopherol: A Fluorescent Form of Vitamin E

  日期：2010.5.7

  Fluorescent nitrobenzoxadiazole analogues of alpha-tocopherol (NBD-alpha-Tocs;lambda(ex) = 468 nm, lambda(em) = 527 nm) have been made previously to aid study of the intracellular location and transfer of vitamin E. However, these analogues are susceptible to photobleaching while under illumination for confocal microscopy as well as in in vitro FRET transfer assays. Here we report the synthesis of three fluorescent analogues of alpha-tocopherol incorporating the more robust dipyrrometheneboron difluoride (BODIPY) fluorophore. A BODIPY-linked chromanol should have no intervening polar functional groups that might interfere with binding to the hydrophobic binding site of the tocopherol transfer protein (alpha-TTP). A key step in bringing the two ring systems together was a metathesis reaction of vinyl chromanol and an alkenyl BODIPY. An o-tolyl containing second generation Grubbs catalyst was identified as the best catalyst for effecting the metathesis without detectable alkene isomerization, which when it occurred produced a mixture of chain lengths in the alkyl linker. C8-BODIPY-alpha-Toc 10c (lambda(ex) = 507 nm, lambda(em) = 511 nm, epsilon(507) = 83,000 M-1 cm(-1)) having an eight-carbon chain between the chromanol and fluorophore, had the highest affinity for alpha-TTP (K-d = 94 +/- 3 nM) and bound specifically as it could not be displaced with cholesterol.
• Synthesis of the Spiroiminal Moiety and Approaches to the Synthesis of Marineosins A and B

  A short and efficient synthesis of model spiroiminals that have the same stereochemistry as marineosins A and B, but different conformations, was carried out in six or seven steps from 6-methyltetrahydropyran-2-one. These spiroiminals were also prepared biomimetically by reduction of an enol ether. A more highly substituted spiroiminal with the same stereochemistry and conformation as marineosin A

  total synthesis of the cyclic prodigiosin derivative 4 is described, which constitutes a potential lead compound for the development of immunosuppressive agents. The key steps of this approach comprise a palladium-catalyzed Suzuki cross coupling reaction of the rather unstable pyrrole boronic acid derivative 17 with the electron rich pyrrolyl triflate 15 followed by a ring-closing metathesis reaction
