New polycyclic aminopyridine compounds which are acetylcholinesterase inhibitors, process for preparing them and their use. The polycyclic aminopyridine compounds correspond to the formula ##STR1## in which the various radicals have the meanings stated in the specification. The process for preparing these compounds is characterized in that ketones of general formula (II) are reacted with aminonitriles of general formula (III) and, if necessary, the compounds of formula (I) are alkylated, aralkylated or acylated, or alternatively the corresponding keto precursor is reduced. The compounds of the general formula (I) are especially suitable for the preparation of medicaments against memory disorders such as senile dementia or Alzheimer's disease.
