3-Aza-5-alkenols undergo selective 7-endo-trig cyclization when treated with a catalytic Pd(II) species, CuCl2 and ArSnBu3 giving 7-aryl-substituted oxazepanes. The intramolecular alkoxylation occurs with formation of a seven-membered ring only when associated with an arylating step. Otherwise, 6-exo-trig reactions, providing morpholine derivatives, were observed.
