The present invention provides compounds of Formula (I) or a stereoisomer or pharmaceutically acceptable salt or solvate form thereof, wherein the variables A, L, Z, X1, X2, X3, X4, and X5 are as defined herein. The compounds of Formula (I) are useful as selective inhibitors of serine protease enzymes of the coagulation cascade and/or contact activation system; for example thrombin, factor Xa, factor XIa, factor IXa, factor VIIa and/or plasma kallikrein. In particular, it relates to compounds that are selective factor XIa inhibitors. This invention also relates to pharmaceutical compositions comprising these compounds and methods of treating thromboembolic and/or inflammatory disorders using the same.
2-halobiaryls with isocyanides was developed. The reaction afforded an array of fluorenone imine derivatives via the cleavage of a C−H bond at the 2′-position of 2-halobiaryls. The use of 2,6-disubstitutedphenyl isocyanide was crucial for this catalytic cyclocoupling reaction to proceed. The reaction was applicable to heterocyclic and vinylic substrates, allowing the construction of a wide range of
为了证明异氰化物在催化CH键官能化反应中的实用性,开发了2-卤代双芳基与异氰化物的钯催化的环偶联反应。该反应通过在2-卤代联芳基的2'-位上的CH键断裂,提供了一系列芴酮亚胺衍生物。2,6-二取代的苯基异氰化物的使用对于进行该催化环偶联反应至关重要。该反应适用于杂环和乙烯基底物,从而允许构建广泛的环系统。观察到的大的动力学同位素效应(k H / k D = 5.3)表明,CH键的活化是该催化作用中的周转限制步骤。

4-(Bromophenyl)pyridines, useful in preparing bactericides, are prepared by reacting a 4-phenylpyridine with bromine in the presence of an excess of a Lewis acid catalyst, preferably aluminum chloride.
Transition metal-catalyzed diamination by hydroxylamines is a common approach for making three-membered aziridines, while its use for building the larger N-heterocycles is still underdeveloped. Herein, we report an efficient Pd(0)-catalyzed inter-molecular [4+1] annulation of o-bromo(or chloro)-biaryls with bifunctional secondary hydroxylamines for the one-step assembly of synthetically useful carbazoles
羟胺的过渡金属催化二化是制备三元氮丙啶的常用方法,而其用于构建较大的N-杂环的用途仍未开发。在此,我们报告了一种有效的 Pd(0) 催化的分子间 [4+1] 环化邻溴(或氯)-联芳基与双功能仲羟胺,用于一步组装合成有用的咔唑。值得注意的是,这种多米诺骨牌反应的关键是明智地选择氨基源和 Pd(0)-催化剂,以便在具有不稳定 NO 的羟胺存在下将芳基卤化物氧化加成到 Pd(0)-物种中。键。
