We describe a triflic acid promoted cascade reaction of adamantanederivatives consisting of a decarboxylation of N-methyl protected cyclic carbamates and a subsequent intramolecular nucleophilic 1,2-alkyl shift to generate ring contracted iminium triflates. This reaction expands the family of similar transformations, such as Wagner–Meerwein-, Demjanov–Tiffeneau-, Meinwald- or (semi-)pinacol-rearrangement
