Synthesis of Aryl Amides from Acyl-Bunte Salts and Aryl Azides

In this study, we developed an efficient method for the synthesis of aryl amides from sodium thiosulfate pentahydrate, organic anhydrides, and aryl azides. Sodium thiosulfate may be used as the sulfur source, which reacts with anhydrides to generate acyl-Bunte salt; this salt reacts with aryl azides...

Zusammenfassung:In this study, we developed an efficient method for the synthesis of aryl amides from sodium thiosulfate pentahydrate, organic anhydrides, and aryl azides. Sodium thiosulfate may be used as the sulfur source, which reacts with anhydrides to generate acyl-Bunte salt; this salt reacts with aryl azides via the in situ generation of thiocarboxylate. Using our method, we successfully synthesized a key bioactive compound. The advantages of one-pot two-step reactions include operational simplicity, structurally diverse products with favorable yields, use of less toxic odorless reagents, and easy applicability to large-scale operations.
