  Fluorinated pyrazole acids are agonists of the high affinity niacin receptor GPR109a

  摘要：

  A series of 5-alkyl pyrazole-3-carboxylic acids were prepared and found to act as potent and selective agonists of the human GPCR, GPR109a, the high affinity nicotinic acid receptor. No activity was observed at the highly homologous low affinity niacin receptor, GPR109b. A further series of 4-fluoro-5-alkyl pyrazole-3-carboxylic acids were shown to display similar potency. One example from the series was shown to have improved properties in vivo compared to niacin. (c) 2007 Elsevier Ltd. All rights reserved.

  [reaction: see text] The dipolarophilic reactivity of enantiopure (Z)-3-p-tolylsulfinylacrylonitriles (1) has been evaluated with diazoalkanes. 3-Cyanopyrazoles are obtained when R = H, but with R = alkyl (Bn, n-Bu, and t-Bu) only one cycloadduct (4 or 5) is formed in high yield under mild conditions, therefore evidencing a complete control of the regioselectivity and the endo/exo and pi-facial selectivities

  [反应：见正文]已用重氮烷评估了对映纯（Z）-3-对甲苯基亚磺酰基丙烯腈（1）的偶极亲和性。当R = H时获得3-氰基吡唑，但当R =烷基（Bn，n-Bu和t-Bu）时，在温和条件下仅以高收率形成一个环加合物（4或5），因此证明了对苯并吡咯的完全控制。区域选择性以及内/外和面部选择性。这些反应是吡唑啉及其相关结构合成的新的直接途径，并揭示了（Z）-亚磺酰基丙烯腈的优异的双亲性特征。
