An efficient proline‐catalyzed synthesis of 4,5‐disubstituted‐ N ‐sulfonyl‐1,2,3‐triazoles has been accomplished from 1,3‐dicarbonyl compounds and sulfonyl azides. The developed reaction is suitable for various symmetrical and unsymmetrical 1,3‐dicarbonyl compounds, tolerates various functional groups and affords 4,5‐disubstituted‐ N ‐sulfonyl‐1,2,3‐triazoles in good yield with excellent regioselectivity. Rhodium‐catalyzed denitrogenative functionalization of 4,5‐disubstituted‐ N ‐sulfonyl‐1,2,3‐triazoles further demonstrates their utility in organic synthesis.
