    • To test this assumption, we attempted to trap the stabilized cation with nucleophilic species. Indeed, treatment of 7 f with boron trifluoride and triethylsilane afforded 12 (51%), by reductive ring cleavage, and oxatriquinane 13 (24%), by isomerization through participation of the phenyl substituent. See the Supporting Information.. (Chemical Equation Presented).
