Amination of Nitro-Substituted Heteroarenes by Nucleophilic Substitution of Hydrogen

An open-air method for the transition metal-free direct amination of nitro(hetero)arenes by anilines is disclosed. In this methodology, an aromatic C-H bond is substituted via oxidative nucleophilic aromatic substitution of hydrogen (ONSH). DFT calculations and mechanistic studies support a dianion pathway with oxidation by molecular oxygen as the rate-limiting step

Discovery of Potent Heterodimeric Antagonists of Inhibitor of Apoptosis Proteins (IAPs) with Sustained Antitumor Activity

The prominent role of IAPs in controlling cell death and their overexpression in a variety of cancers has prompted the development of IAP antagonists as potential antitumor therapies. We describe the identification of a series of heterodimeric antagonists with highly potent antiproliferative activities in cIAP- and XIAP-dependent cell lines. Compounds <b>15</b> and <b>17</b> further demonstrate curative efficacy in human melanoma and lung cancer xenograft models and are promising candidates for advanced studies

Evolution of a Scale-Up Synthesis to a Potent GluN2B Inhibitor and Its Prodrug

This paper describes the efficient scale-up synthesis of the potent negative allosteric glutamate N2B (GluN2B) inhibitor <b>1</b> (BMS-986169), which relies upon a stereospecific S_N2 alkylation strategy and a robust process for the preparation of its phosphate prodrug <b>28</b> (BMS-986163) from parent <b>1</b> using POCl₃. A deoxyfluorination reaction employing bis­(2-methoxyethyl)­aminosulfur trifluoride (Deoxo-Fluor) is also used to stereospecifically introduce a fluorine substituent. The optimized routes have been demonstrated to provide APIs suitable for toxicological studies in vivo
