A new efficient palladium(II)-catalyzed [3,3] aza-Claisen, formal sigmatropic rearrangement of 3-allyloxy-5-aryl-1,2,4-oxadiazoles was developed. The mechanism was studied by analyzing the regiochemicaland stereochemical course of the reaction. The results obtained indicated the intervention of a cationicpallada-cycle similar to the one postulated for the Cope rearrangement of 1,5-dienes.
