5-Bromobarbituric acid

JCR(S)70, 86JHC1439]. The interaction of aminothiones 198 with 5-bromobarbituric acid gives tricyclic compounds 462 (85M633). [Pg.200]

The ring contraction of barbiturates is observed in the course of hydrolytic degradation (Section III,D). N-Substituted barbiturates 151 (R1 = R2 = alkyl, R3 = H) yield the 5-substituted oxazolidine-2,4-dione 152, and N,N-unsymmetrically substituted barbiturates yield a mixture of both 152 and 153. 5-Bromobarbituric acid and its derivatives give a mixture of iminooxazolidin-4-one and hydantoin.409... [Pg.286]
