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。

exclusive formation of products with Z-geometry (across the exo C═C bond) has been confirmed through X-raycrystallography. The methodology also provides an easy access to aristolactams, an important class of natural products. This has been successfully demonstrated by synthesizing two aristolactam derivatives (including Cepharanone B).
