The synthesis of a series of 3-aryl 5-hexenyl amines and the cyclisations of the corresponding N-chloroamines are described. When the ring closure results from the amino radical addition to the ethylenic double bond, 2-chloromethyl 4-phenyl piperidines are obtained. These compounds lead by intramolecular Friedel-Craft reaction to varied substituted 6,7-benzomorphanes. When the phenyl ring is substituted
