  2-Substituted (2SR)-2-Amino-2-((1SR,2SR)-2-carboxycycloprop-1-yl)glycines as Potent and Selective Antagonists of Group II Metabotropic Glutamate Receptors. 1. Effects of Alkyl, Arylalkyl, and Diarylalkyl Substitution

  摘要：

  In this paper, we describe the synthesis of a series of a-substituted analogues of the potent and selective group II metabotropic glutamate receptor (mGluR) agonist (1S,1'S,2'S)-carboxy-cyclopropylglycine (2, L-CCG 1). Incorporation of a substituent on the amino acid carbon converted the agonist 2 into antagonist. Ail of the compounds were prepared and tested as a series of four isomers, i.e., two racemic diastereomers. We explored alkyl substitution, both normal and terminally branched; phenylalkyl and diphenylalkyl substitution; and a variety of aromatic and carbocyclic surrogates for phenyl. Affinity for group II mGluRs was measured using [H-3]glutamic acid (Glu) binding in rat forebrain membranes. Antagonist activity was confirmed for these compounds by measuring their ability to antagonize (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid-induced inhibition of forskolin-stimulated cyclic-AMP in RGT cells transfected with human mGluR2 and mGluR3. We found that while alkyl substitution provided no increase in affinity relative to 2, phenylethyl and diphenylethyl substitution, as in 105 and 109, respectively, were quite beneficial, The affinity of 109 was further enhanced when the two aromatic rings were joined by an oxygen or sulfur atom to form the tricyclic xanthylmethyl and thioxanthylmethyl amino acids 113 and 114, respectively. Amino acid 113, with an IC50 of 0.10 mu M in the [H-3]Glu binding assay, was 52-fold more patent than 2, whose IC50 was 0.47 mu M.

  PPM 级负载三苯基碳四（五氟苯基）硼酸盐对酮类进行可持续的有机催化氰基硅烷化

  摘要：

  随着对可持续均相催化的巨大需求，复杂有机化合物的高效合成和简单纯化的重要性正在引起人们的关注。在此，我们报道了使用三苯甲基四（五氟苯基）硼酸盐 ( [Ph 3 C] + [B(C 6 F 5 ) 4 ] -) 作为一种极其活跃的有机催化剂。固体盐的中性、空气和湿气耐受性有利于用户友好的处理。使用这种不含过渡金属的催化体系，可以通过使用各种酮作为起始原料，以 50 ppm [= 0.005 mol%] 的催化剂负载量获得相应的氰醇三甲基甲硅烷基醚。在既没有温度控制（冷却或加热）也没有柱色谱的无溶剂条件下，克级反应完美进行，通过去除挥发物可以获得高纯度产品。实验和分析研究支持原位生成的具有弱配位阴离子对的硅作为活性催化剂，在优异的反应性中起着至关重要的作用。

  A series of cathinone (alpha-aminopropiophenone) analogues was examined using the isolated rat fundus preparation. (S)-(-)-Cathinone possesses twice the serotonin receptor affinity of (+/-)-cathinone and four times the affinity of racemic amphetamine. Several derivatives of cathinone were found to either possess a lower affinity than the parent compound or did not interact with the receptors in a competitive
