Abstract: A method for the synthesis of cyclic polyamines preceeds by reaction of a diamine with the acrylonitrile wherein the reduction steps are carried out with Raney alloy instead of using hydrogen under pressure in the presence of Raney nickel. Compounds so prepared have the formula: ##STR1## wherein A and B are: an alkyl chain --(CH.sub.2)-- in which x is an integer of 2 to 4, substituted or not by an alkyl group of 1 to 5 carbon atoms, which may be substituted or not by an aromatic ring, heterocyclic ring, amine ketone, carboxylic acid, amide, cyano, alkyl, alkoxy, hydroxy, nitro or halogen and R.sub.1 and R.sub.2 are the same moieties as those substituting the alkyl claim above.
