Hypervalent iodine(III) induced intramolecular cyclization of substituted phenol ethers bearing an alkyl azido sidechain–a novel synthesis of quinone imine ketals
Abstract
A novel and efficient synthesis of quinone imine ketals from substituted phenol ethers bearing an alkyl azido sidechain using a hypervalent iodine(III) reagent, phenyliodine(III) bis(trifluoroacetate)(PIFA), is described.
