  摘要：

  这项工作报告了二芳基噻唑烷-2,4-二酮作为亲核试剂在不对称催化中的首次应用。通过使用基于手性氨基酸的（硫）脲-叔胺作为催化剂，我们相继建立了不对称共轭基团添加到硝基烯烃和亚硫基化成二芳基噻唑烷-2,4-二酮的N-（硫烷基）-琥珀酰亚胺。获得了具有高对映体和非对映体选择性（高达> 99％ee和> 19：1 dr）的两个系列的生物学上重要的5-芳基-5-取代的噻唑烷-2,4-二酮。使用MTT分析发现，富含对映体的加合物对三种不同的癌细胞系显示出令人满意的抗癌活性。所有这些成功都取决于制定通用且合宜的合成策略以提供多种5 H-噻唑烷-2,4-二酮。

  The first cobalt-catalyzed asymmetric Kumada cross-coupling with high enantioselectivity has been developed. The reaction affords a unique strategy for the enantioselective arylation of α-bromo esters catalyzed by a cobalt-bisoxazoline complex. A variety of chiral α-arylalkanoic esters were prepared in excellent enantioselectivity and yield (up to 97% ee and 96% yield). The arylated products were transformed
