    A series of 3-substituted [1,2,4]triazino[4,3-c]benzimidazoles V were prepared and tested at the central benzodiazepine receptor (BzR). These compounds were designed as rigid analogues of the previously described N-benzylindolylglyoxylylamide derivatives IV. The title compounds V showed an affinity which depended directly on the presence of the N(10)-H group and an aromatic ring at position 3. Some
    制备了一系列3-取代的[1,2,4]三嗪[4,3-c]苯并咪唑V,并在中央苯并二氮杂pine受体(BzR)上进行了测试。这些化合物被设计为先前描述的N-苄基吲哚基二烯丙基乙二酰胺衍生物IV的刚性类似物。标题化合物V显示出亲和力,该亲和力直接取决于N(10)-H基团和位置3上的芳环的存在。相对于吲哚基二羟乙酰胺,它们中的一些引起了2倍或3倍的高亲和力。导数IV(R = H)。GABA比和[(35)S]-叔丁基环磷酸硫代酸酯结合数据揭示了化合物1c,e,f,j,k的部分反向激动剂/拮抗剂和2c的部分激动剂的功效谱。该最后的化合物被证明可有效拮抗戊四氮诱导的小鼠癫痫发作。

    challenging but synthetically indispensable approach to α-branched carbonyl motifs that are widely represented among drugs, natural products, and synthetic intermediates. Here, we describe a simple approach to generation of boron enolates in the absence of strong bases that allows for introduction of both α-alkyl and α-aryl groups in a reaction of readily accessible 1,2-dicarbonyls and organoboranes. Obviation
    在α-碳上构建CC键是一种具有挑战性但在合成中必不可少的方法,可用于药物,天然产物和合成中间体中的α-支链羰基。在这里,我们描述了一种在不存在强碱的情况下生成烯醇硼的简单方法,该方法允许在易于获得的1,2-二羰基与有机硼烷的反应中引入α-烷基和α-芳基。避免使用非选择性,强碱性和亲核试剂,可以在亲电体存在的情况下进行反应,亲电体会拦截中间的硼烯醇化物,从而在三组分过程中产生两个新的α-C-C键。
