The esterification of activated amides, N-acylsaccharins, under transition-metal-free conditions with good functional group tolerance has been developed, resulting in C–N cleavage leading to efficient synthesis of a variety of esters in moderate to good yields. This work demonstrates that esterification may proceed by using simple N-acylsaccharins, haloalkanes, and Cs2CO3 as oxygen source.
The first palladium-catalyzed Sonogashira coupling of amides has been developed, which proceeds
