    • This invention provides a concise, asymmetric synthesis of piperazic acid and derivatives thereof, whereby either the (3S)- or (3R)-enantiomeric form may be obtained with high optical purity. (3S)-piperazic acid is derived from D-glutamic acid through an (R)-2,5-dihydroxyvalerate ester intermediate. After the hydroxy groups are converted to suitable leaving groups, such as mesylates, the ester is treated with a bis-protected hydrazine to provide the desired (3S)-piperazic acid derivative. The (3R) enantiomer of piperazic acid may be similarly obtained starting with L-glutamic acid. The method may also be used to obtain piperazic acid derivatives that have moderate optical purity or are racemic. By this method, piperazic acid derivatives may be obtained that are useful as intermediates for pharmacologically active compounds. For example, certain intermediates of this invention are useful for preparing caspase inhibitors, particularly inhibitors of ICE, through additional steps known in the art.
    • 本发明提供哌嗪酸及其衍生物的简明,不对称合成,由此可以以高光学纯度获得(3S) - 或(3R) - 对映体形式。 (3S) - 哌嗪酸通过(R)-2,5-二羟基戊酸酯中间体衍生自D-谷氨酸。 将羟基转化为合适的离去基团(如甲磺酸酯)后,用双 - 保护的肼处理酯,得到所需的(3S) - 哌嗪酸衍生物。 哌嗪酸的(3R)对映异构体可以从L-谷氨酸开始类似地获得。 该方法也可用于获得具有中等光学纯度或外消旋的哌嗪酸衍生物。 通过该方法,可以得到可用作药理活性化合物的中间体的哌嗪酸衍生物。 例如,通过本领域已知的附加步骤,本发明的某些中间体可用于制备胱天蛋白酶抑制剂,特别是ICE的抑制剂。
