Abstract

Spiro compounds 7,11-diaryl-2,4-diazaspiro[5,5]undecane-1,3,5,9-tetraones 3a-d were prepared by carrying out reactions between diarylideneacetones, (ArCH=CH)2C=O, 2a-d [Ar= 2-CH3C6H4, 4-CH3C6H4, 4-(CH3)2NC6H4 and 4-HOC6H4 respectively] and  barbituric acid (1a) under refluxing condition in aqueous ethanol medium without using any catalyst. Under similar conditions the corresponding 7,11-diaryl-3-thioxo-2,4-diazaspiro[5,5]undecane-1,5,9-triones 3e-g were synthesized from the reactions of diarylideneacetones 2a, 2d and 2e [Ar= 4-ClC6H4] with 2-thiobarbituric acid (1b). The structures of the spiro compounds were established with the help of their UV, IR, 1H NMR, 13C NMR and mass spectral data and elemental analyses.
