protocol was developed to construct five- to seven-membered cyclic nitrones through the gold-catalyzed 1,3-azaprotio transfer of allenyloximes under photoirradiation. The photoisomerization of oximes was suggested to convert the inert stereoisomer to a reactive one. This photodriven and gold-catalyzed ring formation could be further extended to the thermodynamically stable aryl ketoximes with an E-configuration
