The action of tert-butylhydroperoxide and tin(IV) chloride upon allylic alcohols containing a lactam ring leads mainly to epoxy alkyl peroxides with high diastereoselection. Both the stereochemistry and the products formed are in marked contrast to the reactions of the analogous carbocyclic allylic alcohols with tert-butyl hydroperoxide-VO(acac)2.

In the presence of pyridinium para-toluenesulfonate (PPTS) an allylic alcohol moiety exocyclic to a lactam ring undergoes allylic isomerisation, or if the solvent is nucleophilic, 1,3-transposition can occur. All the rearrangements occurred with stereocontrol.
