  Discovery of Potent, Orally Available Vanilloid Receptor-1 Antagonists. Structure−Activity Relationship of N-Aryl Cinnamides

  摘要：

  The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators: particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert-butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1): an antagonist that blocks the capsaicin-induced and pH-induced uptake of Ca-45(2+) in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 +/- 5 and 150 +/- 80 nM, respectively. In this report.. we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (F-oral = 39% and 17%. respectively).

• Solvent-free Wittig olefination with stabilized phosphoranes—scope and limitations
  作者：Thies Thiemann、Masataka Watanabe、Yasuko Tanaka、Shuntaro Mataka

  DOI：10.1039/b311894k

  日期：——

  Neat mixtures of arene/hetarenecarbaldehydes, alkanals as well as alkenals with alkyl (triphenylphosphoranylidene)acetates react exothermally to furnish the corresponding alkenes. In certain cases, heating has to be provided externally. Reaction times are short and yields are generally very high. Neat mixtures of ketones and alkyl (triphenylphosphoranylidene)acetates react preferentially under microwave irradiation. The better stabilized phosphoranes do not react in the solid state with aldehydes or ketones under conventional heating, but necessitate microwave irradiation, although not all of the phosphoranes have been found to be stable under microwave irradiation at 500 W (2450 MHz).

  纯净的芳烃/杂芳烃醛、烷醛以及烯醛与烷基（三苯基磷铵基）醋酸酯发生放热反应，生成相应的烯烃。在某些情况下，需要外部加热。反应时间短，产率通常很高。纯净的酮和烷基（三苯基磷铵基）醋酸酯在微波照射下优先发生反应。稳定性较好的磷烷在固态下与醛或酮在常规加热下不反应，而需要微波照射，尽管并非所有的磷烷在500 W（2450 MHz）的微波照射下都被发现是稳定的。
• BF₃·OEt₂-mediated syn-selective Meyer–Schuster rearrangement of phenoxy propargyl alcohols for Z-β-aryl-α,β-unsaturated esters

  日期：——

  1-aryl-3-phenoxy propargyl alcohols is achieved via a BF3-mediated syn-selective Meyer–Schuster rearrangement under ambient conditions. The reaction mechanism is postulated to involve an electrophilic borylation of an allene intermediate as the key step to kinetically control the stereoselectivity.

  通过在环境条件下通过BF 3介导的顺选择性Meyer-Schuster重排，可以从容易获得的1-芳基-3-苯氧基炔丙基醇合成Z -β-芳基-α，β-不饱和酯。假定该反应机理涉及丙二烯中间体的亲电子硼化，这是动力学控制立体选择性的关键步骤。
• Substituent effects of cis-cinnamic acid analogues as plant growh inhibitors

  1-O-cis-Cinnamoyl-beta-D-glucopyranose is one of the most potent allelochemicals that has been isolated from Spiraea thunbergii Sieb by Hiradate et al. It derives its strong inhibitory activity from cis-cinnamic acid (cis-CA), which is crucial for phytotoxicity. By preparing and assaying a series of cis-CA analogues, it was previously found that the key features of cis-CA for lettuce root growth inhibition are a phenyl ring, cis-configuration of the alkene moiety, and carboxylic acid. On the basis of a structure-activity relationship study, the substituent effects on the aromatic ring of cis-CA were examined by systematic synthesis and the lettuce root growth inhibition assay of a series of cis-CA analogues having substituents on the aromatic ring. While ortho- and para-substituted analogues exhibited low potency in most cases, meta-substitution was not critical for potency, and analogues having a hydrophobic and sterically small substituent were more likely to be potent. Finally, several cis-CA analogues were found to be more potent root growth inhibitors than cis-CA. (C) 2013 Elsevier Ltd. All rights reserved.

  A new coupling partner: Vinyl acetate couples with organoboron compounds in the presence of a rhodium catalyst; carbon–carbon bond formation occurs on the vinylic carbon attached to the acetoxy group. Conventional nickel and palladium catalysts were found to be ineffective for the reaction.
