N-Sulfonyl-1,2,3-triazoles react with cyclic N,N’-diaryl aminals under dirhodium catalysis to generate, after ylide formation and subsequent ring opening, original imino-iminium intermediates. Quite a few recent synthetic applications have been reported using these electrophilic moieties, in particular series of cascade reactions forming unprecedented polycyclic polyaza derivatives.
