Abstract
The tandem 1,3-azaprotio cyclotransfer–cycloaddition reaction between aldoximes and divinyl ketone affords the exo-isomers of substituted 1-aza-7-oxabicyclo[3.2.1]octan-4-ones when a substoichiometric amount of hafnium(IV) chloride, zirconium(IV) chloride or aluminium(III) chloride is added.
