Abstract

Silver-catalyzed direct lactonization of 1,4-disubstituted 1,2,3-triazole acids through C(5)–H acyloxylation is reported. This method provides a concise and efficient pathway to synthesize lactone-fused triazole derivatives, which were obtained in good to excellent yields at room temperature.
