| Abstract: | The development of new and practical 3‐pentoxythiocarbonyl auxiliaries for IrI‐catalyzed C?H alkylation of azacycles is described. This method allows for the α‐C?H alkylation of a variety of substituted pyrrolidines, piperidines, and tetrahydroisoquinolines through alkylation with alkenes. While the practicality of these simple carbamate‐type auxiliaries is underscored by the ease of installation and removal, the method's utility is demonstrated in its ability to functionalize biologically relevant l ‐proline and l ‐trans ‐hydroxyproline, delivering unique 2,5‐dialkylated amino acid analogues that are not accessible by other C?H functionalization methods. |
