Novel and efficient syntheses of quinone imine ketals (2aj) and quinone imines (4ah) from substituted phenol ethers (1ak) bearing an alkyl azido side-chain using the combination of hypervalent iodine(III) reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA) and trimethylsilyl trifluoromethanesulfonate (TMSOTf), have been developed.
