  Enantioselective Synthesis of 3,4-Disubstituted cis- and trans-1,2,5-Thiadiazolidine-1,1-dioxides as Precursors for Chiral 1,2-Diamines

  摘要：

  Both, cis- and trans-3,4-disubstituted thiadiazolidines 5 and 6 can enantioselectively be obtained from thiadiazoles 2 which, in turn, are efficiently prepared from the respective 1,2-diketone by an improved protocol. An asymmetric ruthenium-catalyzed transfer hydrogenation followed by a diastereoselective hydride addition furnishes exclusively the cis-isomers 5 which, under acidic conditions, undergo a novel isomerization into the trans-isomers 6. These cyclic sulfamides can be transformed into 1,2-diamines as well as 2,3-diamino acids.

• Synthesis and Cytotoxic Evaluation of Novel Platinum(II) Complexes with<i>C</i>₂-Asymmetric and<i>C</i>₂-Symmetric Chiral Vicinal Diamines

  A series of new platinum(II) complexes with C2‐asymmetric and C2‐symmetric 1,2‐diamines were designed and synthesized by convenient methods, involving samarium diiodide induced reductive coupling as the key step. The results of cytotoxicity showed that compounds (R,R)‐11a and (S,S)‐11a, two novel platinum(II) complexes with asymmetric 1,2‐diamines, exhibited more potent cytotoxicity than that of oxaliplatin

  通过便利的方法设计和合成了一系列具有C 2-不对称和C 2-对称1,2-二胺的新铂（II）配合物，其中关键在于二碘化sa诱导的还原偶联。细胞毒性结果表明，化合物（R，R）-11a和（S，S）-11a是两种具有不对称1,2-二胺的新型铂（II）配合物，对所有白血病细胞的毒性均比奥沙利铂强。线。有趣的是，（R，R）‐ 11a和（S，S）‐图11a显示出对三种实体癌细胞系的活性低于奥沙利铂，这表明这两种化合物可能仅选择性地抑制白血病细胞系。与此相反，（[R ，- [R ）- 15A和（小号，小号） - 15A与对称1,2-二胺，二铂（II）配合物，表现出相似的细胞毒性，以该对所有白血病细胞系和对更有效活性奥沙利铂实体癌细胞系。进一步的流式细胞仪数据表明（R，R）-11a可以明显地使白血病K562细胞停滞在G2 / M期。
