  Lipase-catalyzed enantioselective hydrolysis of N-acyloxymethyl groups in organic solvent: syntheses of chiral 5,5-disubstituted 1-methylbarbiturates

  摘要：

  Chiral 5,5,-disubstituted N-acyloxymethylbarbiturates have been obtained in 40-99% optical yields by lipase-catalyzed hydrolyses of 5,5-disubstituted bisacyloxymethylbarbiturates in H2O-saturated diisopropyl ether. These chiral barbiturates were readily converted into the corresponding chiral N-methylbarbiturates such as (R)-(-)-mephobarbital and (S)-(+)-hexobarbital.
