Iridium‐catalyzed C−H activation and cyclization of naphthalen‐1‐amines with diazo compounds leading to naphtho[1,8‐bc]pyridines have been developed. Different from the previous free‐amine‐directed C−H functionalization with diazo compounds that relied on the coordination of lone pair electrons or in situ formation of imine, this transformation passes through a five‐membered iridacycle intermediate containing an
已经开发了铱催化的CH-1活化和萘-1-胺与重氮化合物的环合反应,从而生成萘[1,8- bc ]吡啶。与以前的重氮化合物基于孤对电子的配位或亚胺的原位形成的重氮化合物的游离胺定向的CH官能化不同,该转化过程通过包含N-Irσ-键的五元iridacycle中间体进行。 。它为在温和条件下合成有用的各种萘并[1,8- bc ]吡啶衍生物提供了另一种方法。
Cobalt-Catalyzed Direct Carbonylative Synthesis of Free (<i>NH</i>)-Benzo[<i>cd</i>]indol-2(1<i>H</i>)-ones from Naphthylamides
cobalt-catalyzed C–H carbonylation of naphthylamides for the synthesis of benzo[cd]indol-2(1H)-one scaffolds has been developed. The reaction employs a traceless directing group and uses benzene-1,3,5-triyl triormate as the CO source, affording various free (NH)-benzo[cd]indol-2(1H)-ones in moderate to high yields (up to 88%). Using this protocol, the total synthesis of BET bromodomain inhibitors A and B was accomplished
已开发了钴催化的萘甲酰胺的CH羰基化反应,用于合成苯并[ cd ]吲哚-2(1 H)-一个支架。该反应采用无痕导向基团,并使用苯甲酸1,3,5-三甲酸三乙酯作为CO源,以中等至高收率提供各种游离的(NH)-苯并[ cd ]吲哚-2(1 H)-(高达88%)。使用该方案,也完成了BET溴结构域抑制剂A和B的总合成。

Electrooxidative peri-C–H activation was accomplished by versatile ruthenium(II) catalysis in terms of C–H/N–H and C–H/O–H functionalization. Thus, alkyne annulations proved viable with ample scope by organometallic C–Hactivation. The sustainable electrocatalysis exploited electricity, thereby avoiding the use of toxic transition metals as sacrificial oxidants. The robust ruthenium(II)-electrocatalysis
Electrooxidative围-C-H活化是由通用的钌(完成II)催化的C-H / N-H和C-H / O-H官能的条款。因此,通过有机金属的C–H活化,炔烃环行证明在足够的范围内是可行的。可持续的电催化利用电力,从而避免使用有毒的过渡金属作为牺牲氧化剂。鲁棒的钌(II)电催化作用在质子醇/ H 2 O反应介质中,具有极好的位置,区域和化学选择性。
