Chiral 5, 5-disubstituted N-acyloxymethylbarbiturates have been obtained in 40-99% optical yields by lipase-catalyzed hydrolyses of 5, 5-disubstituted N, N'-bisacyloxymethylbarbiturates in H2O-saturated diisopropyl ether. These chiral barbiturates were readily converted into chiral drugs, mephobarbital, hexobarbital and febarbamate.
手性5, 5-二取代N-酰基氧甲基巴比妥酸酯通过在H2O饱和的二异丙醚中进行的脂肪酶催化水解反应,获得了40-99%的光学产率。 这些手性巴比妥酸酯可以很容易地转化为手性药物美福巴比妥、己巴比妥和菲巴美特。
