چکیده
The title compound, C(16)H(8)O(3), was synthesized by the Pd-coupling reaction of phenyl-acetyl-ene with 4-bromo-phthalic anhydride. The phenyl and isobenzofurane rings are nearly coplanar, forming a dihedral angle of 6.70 (10)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by C-H⋯O hydrogen bonds.

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...
