چکیده
The title compound, C(20)H(14)N(2)O(4)·H(2)O, was synthesized by the reaction of fluorescein and hydrazine hydrate in ethanol. In the crystal structure, the organic mol-ecules are linked into extended two-dimensional networks by inter-molecular hydrogen bonding. Additional face-to-face π-π stacking inter-actions between the phenolic benzene rings in two adjacent mol-ecules [centroid-to-centroid separation = 3.773 (3) Å] link the mol-ecules into a three-dimensional framework.

A series of spiro[isoindole-1,5-isoxazolidin]-3(2H)-ones has been synthesized by 1,3-dipolar cycloaddition of N-benzylnitrone with isoindolin-3-methylene-1-ones. The regio- and stereoselectivity of the process have been rationalized by computational methods. The obtained compounds show cytotoxic properties and antiproliferative activity in the range of 9-22 μM. Biological tests suggest that the...
