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.

obtained for the 9-ethyl derivative rac-20, previously prepared by our group. More bulky substituents at position9 led to less active compounds, although some of them [9-isopropyl (rac-22), 9-allyl (rac-23), and 9-phenyl (rac-26)] show activities similar to that of THA. Substitution at position 1 or 3 with methyl or fluorine atoms always led to more active compounds. Among them, the highest activity

A synthesis of 7-alkylbicyclo[3.3.1]non-6-en-3-ones4b-f and 4j, k by reaction of the corresponding 3-alkyl-2-oxaadamant-1-yl mesylates3 with silica gel in methylene chloride at room temperature, is described. The method failed to give enones4a, g and the related compounds4l, m, what can be rationalized on mechanistic grounds.
