These compounds are represented by formula (I), in which each of R1 and R2=H, C1-C8 alkyl, C3-C7 cycloalkyl, or aromatic; (when R1=H, R2 can be an amine function-protecting radical, amino acid residue or peptide fragment; R1 and R2 being capable of forming, with N, a 5-7 component ring); A=carbonyl or methylene; W=hydroxy, phenoxy, C1-C8 alkoxy; phenoxy(C1-C8 alkyl), amino, (C1-C8 alkyl)amino, di(C1-C8 alkyl)amino, (when A=carbonyl, W=amino acid residue or peptide fragment); Y=-OSO2OR3(II), -OPO(OR3)2 (III), -(CH2(m-SO2OR3 (IV) or -(CH2)m-PO(OR3)2 (V) [R3=H, C1-C8 alkyl; m=1 to 4]; Z=cyclohexane, pyridyl or phenyl; n=0 to 4; on the condition that when Y=(II) or (III), -A-W is other than a sequence composed of natural amino acids. They have antipsychotic properties, an effect facilitating the memorization processes, analgesic properties; they are useful as anorexia-producing agents, and they have stimulatory effects on intestinal motility. <IMAGE> (I)
