The condensation of per(trimethyl)silylbarbital and -phenobarbital with 1,2,3,4,6-penta-O-acetyl-beta-D-glucopyranose in the presence of stannic chloride in dichloroethane gave moderate yields of the beta-coupled barbiturate N-D-glucopyranosyl derivatives. Reaction of metharbital and mephobarbital under the same conditions was unsuccessful. The homologous N-methylglucosides were prepared by reaction of the barbital and phenobarbital N-glucosyl derivatives with diazomethane. The diastereomers of the phenobarbital and mephobarbital derivatives were resolved by use of C-18 reverse-phase h.p.l.c. 1H- and 13C-n.m.r. spectroscopy, and thermospray 1.c.-m.s. proved to be the most useful methods for characterizing the barbiturate glucosides.
