Introduction Since Zhang and co-workers reported the first generation of highly electrophilic α-carbonyl carbenes via gold-catalyzed intermolecular oxidation of alkynes by N-oxides in 2010,1 a wide range of useful synthetic transformations based on this strategy have been reported in the literature.2 Significant advances in this field have been achieved using alternative oxidants such as sulfoxides,3 nitrones,4 nitro-containing compounds,5 isoxazoles and anthranils,6 epoxides,7… The oxidation...
