Popis: Subjection of ω-unsaturated iminium salts 1 to dissolving metal reduction with samarium diiodide in the presence of camphorsulfonic acid afforded the corresponding α-amino radicals 2 , which underwent facile cyclization via a 5 - exo mode of closure leading to heterocyclic products of the general type 4 .
