    摘要:
    Ir/spiro[4,4]-1,6-壬二烯基膦-恶唑啉配体 (SpinPHOX) 配合物催化 3,6-二亚烷基-1,4-二甲基哌嗪-2,5-二酮的双不对称氢化开发,提供高效和实用的途径以高产率获得各种手性 3,6-二取代-2,5-二酮哌嗪,具有独特的顺式非对映选择性和优异的对映选择性(>99% de,高达 98% ee)。该协议的合成效用已在 6a 的克级合成和手性产品 8、14 和 17 以及 2-丁烯基桥连双环二酮哌嗪 10 和羟基二酮哌嗪 11 的有效构建中得到证明。 使用类似的非手性 Ir 催化剂,对映纯单氢化中间体 7a 的氢化得到 cis-6a 作为唯一的产物,表明标题转化的第二步氢化是手性底物控制的过程。5a 的不对称加氢 (AH) 的反应曲线研究表明,单加氢中间体 7a 的浓度在加氢过程中保持在低水平 (<8%)。5a 到 6a 的加氢速度明显快于其半加氢中间体 (S)-7

    Two diketopiperazines, XR334 (1) and the novel compound XR330 (2), were isolated from the lyophilised biomass of an unidentified Streptomyces sp. Their structures were elucidated on the basis of spectroscopic studies and confirmed by chemical synthesis. Both compounds inhibited plasminogen activator inhibitor-1 activity in an amidolytic assay of tissue plasminogen activator mediated plasmin generation. Compound 1 also enhanced fibrinolysis ex vivo and protected against thrombus formation in the rat. These diketopiperazines represent the first low molecular weight inhibitors of plasminogen activator inhibitor-1, a physiological regulator of fibrinolysis
