There are disclosed compounds having the formula
wherein n is 1-4; R₁ is hydrogen, alkyl, aryl, arylloweralkyl, naphthyl, furyl, thienyl, pyridinyl or pyrrolyl; A is a direct bond or (CHR₃)m, m being 1-3; X is hydrogen, loweralkyl, cycloalkyl, loweralkoxy, halogen, hydroxy, nitro, trifluoromethyl, formyl, loweralkylcarbonyl, arylcarbonyl, -SH, loweralkylthio, -NHCOR₄ or -NR₅R₆, R₄ being hydrogen or loweralkyl, and R₅ and R₆ being independently hydrogen, loweralkyl or cycloalkyl; Y is CH₂, O, S or NR₇; and each R₂, each R₃ and R₇ are independently hydrogen, loweralkyl or arylloweralkyl or taken two at a time form a methylene or ethylene bridge constituting a part of a five-membered or larger ring, with the proviso that when Y is CH₂, R₂ and R₃ must together constitute a methylene or ethylene bridge; stereo, optical and geometrical isomers thereof, and pharmaceutically acceptable acid addition salts thereof, which are useful for enhancing memory.
