چکیده
In the title compound, C15H19N3O2, the piperazine ring adopts a chair conformation, with its N-C bonds in pseudo-equatorial orientations. The dihedral angle between the C atoms of the piperazine ring and the phthalamide ring system (r.m.s. deviaiton = 0.008 Å) is 89.30 (8)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, generating a three-dimensional network and aromatic π-π inter-actions also occur [centroid-centroid distances = 3.556 (1)-3.716 (1) Å].

In the title compound, C(26)H(43)N(7)O, each piperazine ring adopts a chair conformation. Two 1-methyl-piperazine rings bond to one Csp(3) of the pyrrole ring via the piperazine N atoms, while the third one links to the N atom of the indolin-2-one unit through a flexible ethyl group with an almost syn conformation. In the crystal, mol-ecules are connected through methyl-ene-carbonyl C-H⋯O inter...
متن کاملImpact of aromatic substitution on the anticonvulsant activity of new N-(4-arylpiperazin-1-yl)-alkyl-2-azaspiro[4,5]decane-1,3-dione derivatives.
A series of N-[(4-arylpiperazin-1-yl)-alkyl]-2-azaspiro[4.5]decane-1,3-dione derivatives were synthesized and evaluated for their anticonvulsant and neurotoxic properties. The main modifications to that series of compounds consisted in the introduction of an aromatic area to the cyclohexane ring as a flexible fragment with conformational freedom (1a-h), or as a rigidified skeleton (2a-h). Excep...

A series of twenty new N-[(4-arylpiperazin-1-yl)-propyl]-2-aza-spiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives were synthesized and their anticonvulsant activity was evaluated in maximal electroshock (MES) and sc pentertazole (sc PTZ) tests. Their neurotoxicity was examined as well. Although no antiseizure properties of the investigated compounds were found in the MES model, eight of th...

The title compound, C(28)H(20)N(2)O(8), was synthesized by the reaction of isobenzofuran-1,3-dione and 2-amino-ethanol in a one-pot reaction. The benzene and five-membered rings are slightly twisted to each other, making dihedral angles of 2.77 (9) and 1.77 (10)°. The rings of the phthalimide groups make dihedral angle of 57.64 (7) and 83.46 (7)° with the central benzene ring. Weak C-H⋯O, C-H⋯π...

In the mol-ecule of the title compound, C(20)H(16)N(2)O(5), the phthalimide fragments are almost planar, with r.m.s. deviations of 0.018 and 0.020 Å, and make a dihedral angle of 53.64 (3)°. The mol-ecular and crystal structures are stabilized by a weak inter-molecular C-H⋯O, C-H⋯π and C=O⋯π [2.883 (1) Å] inter-actions and aromatic π-π stacking inter-actions with a centroid-centroid distance of...
