The present invention relates to macrocyclic compounds of Formula I:
or pharmaceutically acceptable salts thereof or quaternary ammonium salts thereof wherein constituent members are provided hereinwith, as well as their compositions and methods of use, which are JAK/ALK inhibitors useful in the treatment of JAK/ALK-associated diseases including, for example, inflammatory and autoimmune disorders, as well as cancer.

An enantioselective cooperative process involving the concerted/simultaneous action of three different catalysts i.e. Au(I)/amine/chiral Bronsted acid catalysts has been realized for the synthesis of 2-substituted tetrahydroquinolines from 2-aminobenzaldehydes and terminal alkynes.

aminoquinolines: A gold(I)‐catalyzed unprecedented rearrangementreaction between 2‐aminobenzaldehydes with propargyl amine was studied. The study provided, for the first time, direct access to 3‐aminoquinolines in one step starting from readily available starting materials (see scheme). Elegantly designed experiments were employed to unravel the mechanism of this unprecedented rearrangement, which are corroborated

Quinoline derivatives are important natural products and pharmaceuticals, but their synthesis can be challenging due to poor yields, harsh reaction conditions, and instability of starting materials. Here we report the chemoenzymatic synthesis of quinaldic acids under mild conditions using an aldolase, trans-o-hydroxybenzylidenepyruvate hydratase-aldolase (NahE, or HBPA). A series of 2-aminobenzaldehydes
喹啉衍生物是重要的天然产物和药物,但由于收率低、反应条件苛刻和起始材料不稳定,它们的合成具有挑战性。在这里,我们报告了使用醛缩酶、反式-o-羟基亚苄基丙酮酸水合酶-醛缩酶(NahE 或 HBPA)在温和条件下化学酶法合成喹哪二酸。在 NahE 存在下,一系列源自相应硝基类似物还原的 2-氨基苯甲醛与丙酮酸反应,以高达 93% 的分离产率得到取代的喹啉。该反应不同于体内NahE 催化的羟醛缩合,而是类似于由其同源物二氢吡啶二羧酸合酶催化的杂环形成。
