  New 5-substituted-1-(2-hydroxybenzoyl)-benzotriazoles, potassium channel activators. IV

  摘要：

  This paper reports the synthesis of a series of new 5-substituted-1-(2-hydroxybenzoyl)-benzotriazoles, which have been tested for their activity as possible activators of potassium channels. In rat aortic rings, the 'opened' derivatives 1a-f, intermediates of synthesis, showed vasorelaxing properties, with appreciable values of potency. However, the most remarkable effects were recorded for the 2-hydroxybenzoylbenzotriazoles 3a-f, which showed full vasorelaxing efficacy and high potency values. The introduction of a 2-hydroxybenzyl substituent in the 1 position of the benzotriazole ring (compound 7) strongly decreased the activity, showing the importance of the electron-acceptor carbonyl function. The best compound, 3b, was further investigated, in order to evaluate the possible mechanism of action involved in the vasodilator activity. In the vascular model, different potassium channel blockers inhibited the effects of the compound, and an increase of the levels of membrane depolarisation induced a significant reduction of the recorded responses. Compound 3b was also tested in a model of isolated rat heart, retroperfused through the aorta and submitted to a global ischemia/reperfusion cycle. In such an experimental condition, 3b showed an interesting cardioprotective activity. All the above observations are in agreement with the hypothesis of a mechanism linked to the activation of potassium channels. (C) 2001 Elsevier Science S.A. All rights reserved.

  微波辅助的苯乙炔-点击化学：1 H-苯并[ d ] [1,2,3]三唑的制备

  摘要：

  苯并三唑是通过将各种叠氮化物进行三组分和两组分微波辅助的[3 + 2]环加成反应制得的。在三组分反应中，在原位制备的叠氮化物存在下，通过邻（三甲基甲硅烷基芳基）三氟甲磺酸酯与CsF或KF / 18-Crown-6的反应生成芳烃。然而，在两组分反应中，在生成芳烃之前，将新鲜制备的叠氮化物添加到反应容器中。当微波辅助反应在125°C下进行时，在15–20分钟内可获得良好至优异的苯并三唑收率。这些反应时间比使用常规加热进行的类似反应快得多。

  [3+2] cycloadditions of various azides to benzyne, 3-methoxybenzyne, and 4,5-difluorobenzyne. In the three-component reaction, the aryne is generated, in the presence of an azide prepared in situ, by the reaction of an o-(trimethylsilylaryl) triflate with either CsF or KF/18-Crown-6. However, in the two-component reactions, a freshly prepared azide is added to the reaction vessel prior to aryne generation
