migratory rearrangement reactions of 2-oxypyridines with N-sulfonyl-1,2,3-triazoles have been developed under rhodium catalysis, providing a reliable and efficient protocol for accessing N-substituted 2-pyridones. These two distinct rearrangements feature the controllable 1,4-migration of a carbonate group from O-to-C as well as the O-to-N 1,6-migration of an acyl group via α-imino rhodium carbene transfer

A novel rhodium‐catalyzed dearomatization of O‐substituted pyridines to access N‐substituted 2‐pyridones has been developed. A computational study suggests a mechanism involving the formation of a pyridinium ylide followed by an unprecedented 1,4‐acyl migratory rearrangement from O to C. Furthermore, the chiral dirhodium complexes serve as the catalyst for the asymmetric transformation with excellent
Substituted sulfonamide compounds corresponding to formula I:
a process for their preparation, pharmaceutical compositions comprising such compounds, and the use of such substituted sulfonamide compounds in pharmaceutical compositions for the treatment of pain or other disorders or diseases that are mediated at least in part by B1R receptors.
