  N-Arylpiperazinyl-N‘-propylamino Derivatives of Heteroaryl Amides as Functional Uroselective α₁-Adrenoceptor Antagonists

  摘要：

  Novel arylpiperazines were identified as alpha(1)-adrenoceptor(BR) subtype-selective antagonists by functional in vitro screening. 3-[4-(ortho-Substituted phenyl)piperazin-1-yl]propylamines were derivatized with N,N-dimethyl anthranilamides, nicotinamides,;as well as carboxamides of quinoline, I,8-naphthyridine, pyrazolo[3,4-b]pyridine, isoxazolo[3,4-b]pyridine, imidazo[4,5-b]pyridine, and pyrazolo[1,5-a]pyrimidines. Strips of rabbit bladder neck were employed as a predictive assay for antagonism in the human lower tract. Rings of rat aorta;a were used as a ''negative screen'' for the test antagonists. Binding to alpha(1)-ARs was relatively sensitive to size and electronic features of the arylpiperazine portion of the antagonists and permissive to these features on the heteroaryl carboxamide side. These structure-affinity findings were exploited to produce nicotinamides (e.g, 13ii and 25x) and pyrazolo[3,4-b]pyridines (e.g. 37f and 37y) ligands with nanomolar affinity at the alpha(1)-AR subtype prevalent in the human lower urinary tract (pA(2) values: 8.8, 10.7, 9.3, and 9.9, respectively) and displaying 2-3 orders of magnitude selectivity over the alpha(1D)-AR.

  具有最接近硅的官能团的有机硅化合物：XVII。α，β-环氧烷基硅烷和相关的α-杂取代环氧化物锂化的合成和机理方面

  摘要：

  已经发现一系列α-杂取代的环氧化物在环氧化物的CH键处在-75至-115℃的温度范围内锂化。取代基Z可以是Me 3 Si，Ph 3 Si，n-Bu 3 Sn，Ph 3 Sn，PhSO 2，（OEt）2 PO和Ph。基团R和R'为H，Ph和nC 6 H 13；在THF或TMEDA供体介质中，锂化试剂为正丁基锂，​​叔丁基锂和二异丙基氨基锂。在保持构型的情况下发生锂化，并且所得的硫代环氧化合物在0℃以上不稳定，并以类胡萝卜素的方式分解。除了Z和R（烷基或芳基）为顺取向; 其中Z = R 3 Sn，通过锡-锂而不是氢-锂交换发生锂化。由此产生的硫代环氧化合物可以用各种试剂淬灭以产生环氧化合物，其中环氧化合物H已被D，Me 3 Sn，R，RCO和COOH代替。强调了该方法在有机合成中的实用性。最后，考虑并评估了这种α-杂取代环氧化物的酸度和衍生的硫代环氧化合物的相对稳定性的可能解释。
