Novel substituted 11-amino-undeca-4,8-dienal and 11-amino-undecanal aldehyde-derivatives of the formulae Ia ##STR1## in which R.sub.1 to R.sub.6, Y and m are as defined in patent claim 1, and processes for their preparation are described. The compounds of the formulae Ia and Ib can be catalytically hydrogenated to novel 1,11-diaminoundecanes, which, in turn, can be used, for example, for the preparation of polycondensation products, in particular transparent polyamides, or as curing agents for epoxide resins.
