A class of terphenyl compounds is described for use in treating inflammation and inflammation-related disorders. Compounds of particular interest are defined by Formula II: ##STR1## wherein each of R.sup.2 and R.sup.3 is independently selected from hydrido and halo; or wherein R.sup.2 and R.sup.3 together form --OCH.sub.2 O--; wherein each of R.sup.6 through R.sup.8 is independently selected from hydrido, lower alkyl, halo, lower alkoxy, lower haloalkyl, and lower dialkylamino; or wherein R.sup.6 and R.sup.7 together form --OCH.sub.2 O; and wherein R.sup.12 is selected from lower alkylsulfonyl and aminosulfonyl; or a pharmaceutically-acceptable salt thereof.
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。

Les composés d'un intérêt particulier sont définis par la formule (III) dans laquelle chaque R11 à R13 est choisi séparément parmi hydrido, halo, alcoxy inférieur, haloalkyle inférieur, amino, alkylamino inférieur, dialkylamino inférieur et haloalcoxy inférieur; ou bien R11 et R12 forment ensemble -O(CH2)nO-, où n est égal à 1 ou 2; ou alors un sel de ces composés acceptable sur le plan pharmaceutique.
