Article abstract of DOI:10.1055/s-2002-34369

The reaction of propargylic and allylic aminals with trifluoromethanesulfonic anhydride at low temperature produces imminium salts, which react in the presence of N-methylpyrrolidinone (NMP) with functionalized arylmagnesium compounds, providing polyfunct
