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。
