Dichlorocyclopropanation of 2-amino-1,3-dienes affords 1-alkenyl-1-amino-2,2-dichlorocyclopropanes which undergo silver-assisted 2-π electrocyclic opening to furnish 3-aminopentadienyl cations. Nazarov-type cyclization of these intermediates leads to cyclopentenone iminium salts, which provide allylic amines upon reduction. This process, the imino version of the traditional Nazarov reaction, can also be combined with an interrupted Nazarov domino process to give polycyclic amines.
