There are described compounds of the formula
-R₃ and R₄ being independently -H, loweralkyl, -CHO, -CH=CH₂, -CH=CH-loweralkyl, -CH=CHCO₂C₂H₅, -CH₂N(C₂H₅)₂ or
-R₁ when existent is -H, loweralkyl, -CH₂C=CH,
R₅ being methyl or phenyl optionally mono-substituted with loweralkyl or loweralkoxy;
-R₂ when existent is loweralkyl or -CH₂C=CH;
-X is -H, loweralkyl, loweralkoxy, halogen or trifluoromethyl; and
the two -Y groups when existent are both -H, or combine to constitute -(CH₂)₄-;
which compounds are useful as analgesic agents, and for treating various memory dysfunctions characterized by decreased cholinergic function such as Alzheimer's disease.
