involving the S donor atom and surprisingly in bidentate coordination mode a deprotonated thiourea nitrogen resulting in a 4‐membered ring structure around the metal center. DFT calculations were used to explain the differences in coordination behavior. These were complemented by stability studies and biological investigations of the compounds as anticancer agents. Several of the synthesized derivatives

through a series of chemoselective modifications, giving rise to a wide range of thiazolidine frameworks of structural complexity. In particular, the reductive cyclization of 2-nitrobenzyl-substituted 2-iminothiazolidines furnished novel spiroquinolones in good to fair yields. The structural assignment of key products was unequivocally achieved by X-ray diffraction analysis and two-dimensional NMR techniques
开发了通过碱介导的多米诺亲核置换/分子内抗迈克尔加成过程合成各种功能化的 2-亚氨基噻唑烷和相关杂环的方法,该过程涉及缺电子的烯丙基溴化物和衍生自硫脲的 1,3-环位亲核试剂。这些转化在温和简单的条件下进行,并且对不同的官能团具有良好的耐受性。该协议的范围和限制取决于所涉及的烯丙基溴化物和 1,3-ambident 亲核试剂的结构。通过一系列化学选择性修饰进一步证明了 2-亚氨基噻唑烷的合成多功能性,从而产生了结构复杂的各种噻唑烷骨架。特别是,2-硝基苄基取代的2-亚氨基噻唑烷的还原环化以良好至公平的产率提供了新型螺喹诺酮类药物。通过 X 射线衍射分析和二维 NMR 技术明确实现了关键产品的结构分配。
