  6-Methoxy-7-benzofuranoxy and 6-Methoxy-7-indolyloxy Analogues of 2-[2-(2,6-Dimethoxyphenoxy)ethyl]aminomethyl-1,4-benzodioxane (WB4101):1 Discovery of a Potent and Selective α_1D-Adrenoceptor Antagonist

  摘要：

  Previous results have shown that replacement of one of the two o-methoxy groups at the phenoxy residue of the potent, but not subtype-selective, alpha(1)-AR antagonist (S)-WB4101 [(S)-1] by phenyl, or by ortho,meta-fused cyclo-hexane, or especially by ortho,meta-fused benzene preferentially elicits alpha(1D)-AR antagonist affinity. Such observations inspired the design of four new analogues of 1 bearing, in lieu of the 2,6-dimethoxyphenoxy residue, a 6-methoxy-substituted 7-benzofuranoxy or 7-indolyloxy group or, alternatively, their corresponding 2,3-dihydro form. Of these new compounds, which maintain, rigidified, the characteristic ortho hetero-disubstituted phenoxy substructure of 1, the S enantiomer of the dihydrobenzofuranoxy derivative exhibited the highest alpha(1D)-AR antagonist affinity (pA(2) 9.58) with significant alpha(1D)/alpha(1A) and alpha(1D)/alpha(1B) selectivity. In addition, compared both to alpha(1D)-AR antagonists structurally related to 1 and to the well-known alpha(1D)-AR antagonist BMY7378, this derivative had modest 5-HT1A affinity and neutral alpha(1)-AR antagonist behavior.

  small molecules, benzyloxy and phenoxy acids, as potent inhibitors of hemoglobin S (HbS) gelation. Structural modifications with a large number of each class confirm our earlier work that the highest activity is observed with compounds that contain dihalogenated aromatic rings with attached polar side chains. We have also found a halogenated aromatic malonic acid derivative to be quite active. Compounds

  在本文中，我们进一步确立了两类小分子，即苄氧基和苯氧基酸的活性，它们是血红蛋白S（HbS）凝胶化的有效抑制剂。每个类别都有大量结构修饰，这证实了我们较早的工作，即发现含有带有连接的极性侧链的二卤代芳环的化合物具有最高的活性。我们还发现卤代芳族丙二酸衍生物非常活泼。将本文报道的化合物与我们实验室研究的其他抗胶凝剂进行了比较。关于四种衍生物的抗胶凝活性和结合位点及其对血红蛋白（Hb）功能的变构机制的影响进行了评论。

  Herein, we describe a method to produce (Z)-trifluoromethyl enol esters via the olefination and trifluoromethylation of carboxylic acids with TMSCF3. This synthetic method uses inexpensive and easy-to-handle TMSCF3. It employs a commercially available CuCl catalyst to transform a broad range of carboxylic acids into versatile (Z)-trifluoromethyl enol esters with good regio- and stereoselectivity. This protocol

  在此，我们描述了一种通过用 TMSCF 3对羧酸进行烯化和三氟甲基化来生产 ( Z )-三氟甲基烯醇酯的方法。这种合成方法使用廉价且易于处理的 TMSCF 3。它采用市售的 CuCl 催化剂将多种羧酸转化为具有良好区域选择性和立体选择性的多功能 ( Z )-三氟甲基烯醇酯。该协议允许直接从羧酸中简洁地合成高度功能化的 ( Z )-三氟甲基烯醇酯。
