    摘要: Compounds of general formula: ##STR1## where: Ar=phenyl or beta-naphtyl, or aromatic heterocyclic 6-membered ring containing one or two nitrogen atoms;R.sub.1 =one or more substituents of the Ar nucleus, preferably in para position, and selected out of the group consisting of H, CH.sub.3, CH.sub.2 --CH--(CH.sub.3).sub.2, O--CH.sub.3, Cl, F, Br, CF.sub.3, NH.sub.2, S--CH.sub.3, CN, NO.sub.2 R.sub.2 =H, CH.sub.3, C.sub.2 H.sub.5, CH(CH.sub.3).sub.2 ;R.sub.3 = ##STR2## Where R.sub.4 =H, CH.sub.3, C.sub.2 H.sub.5 R.sub.5 =H, CH.sub.3X=none O, S, NH, NCH.sub.3, --CH=CH--, --C.ident.C--Y=O, NH,both in the racemic Form and in the isomeric enantiomeric forms,which produce a nootropic effect, i.e. memory enhancement and learning facilitation, as well as an analgesic effect.
