Isoindolinones are ubiquitous structural motifs in natural products and pharmaceuticals. Establishing an efficient method for structural modification of isoindolinones could significantly facilitate new drug development. Herein, we describe copper-promoted direct amidation of isoindolinone scaffolds mediated by sodium persulfate. The method exhibits mild reaction conditions and high site-selectivity, and enables the structural modification of the drug indobufen ester with various amides with yields of 49 to 98%. It is also gram-scalable. Additionally, the reaction mechanism appears to involve a radical and a carbocationic pathway.

Copper-catalyzed C-N coupling in the synthesis of integrase inhibitors of immunodeficiency viruses
Lin, Jinguan,Houpis, Ioannis N.,Liu, Renmao,Wang, Youchu,Zhang, Jianqian
, p. 205 - 214 (2014/05/20)
This contribution describes the total synthesis of a complex macrocyclic integrase inhibitor, a key enzyme involved in the infection process of various immunodeficiency viruses. The key transformation of the synthetic strategy was the selective C-N coupling of a sulfonamide to a heteroaryl bromide in the presence of potentially competing amide and carbamate functionalities. The transformation was accomplished with CuI catalysis using bypiridine as the ligand in the presence of base and enabled a convergent approach to the target molecule.

Based on the structural features of Indoprofen and PIB, a series of isoindol-1,3-diones 1a-k and isoindol-1-ones 2a-l were designed and synthesized. These 23 compounds were evaluated by competitive binding assay against aggregated Aβ42 fibrils using [125I]TZDM. All the isoindolone derivatives showed very good binding affinities with Ki values in the subnanomolar range (0.42-0.94 nM). Among them, isoindol-1,3-diones 1i and 1k and isoindol-1-ones 2c and 2i exhibited excellent binding affinities (Ki = 0.42-0.44 and 0.46-0.49 nM) than those of Indoprofen (Ki = 0.52 nM) and PIB (Ki = 0.70 nM). These results suggest that isoindolones could be served as a scaffold for potential AD diagnostic probes to monitor Aβ fibrils.
