Absztrakt (kivonat)
A convenient and efficient approach toward the synthesis of six 3-(4-substituted benzyl)-6,7- benzo-1,3-diazaspiro[4.5]decane-2,4-diones (1‒6) by Bucherer-Bergs reaction and further alkylation at position 3 of the hydantoin ring is reported. Further, their chemical structure was confirmed by melting points, elemental analysis, FT-IR, NMR and UV–Vis spectroscopic methods. To gain an insight into interactions which the investigated spirohydantoins establish with their environment, their absorption spectra were recorded in selected solvents of different polarity and the solvent effects on the UV-Vis absorption band positions, intensity and shape, were discussed. Substiuent effects on the solvatochromism of compounds 1−6 were analyzed using the Hammett's equation. Considering the broad applications of hydantoin derivatives, as well as the fact that their relative importance may increase in the future, results obtained in this study serve as a basis for further investigations.
