nitro–alkyne cycloisomerization leading to isatogens. Since the first documentation of this reaction by Baeyer (picture of Baeyer and the corresponding literature citation are shown) in the late 19th century, a mild and general method for the synthesis of isatogens has been sought. The electrophilic PdII halide complexes are found to bring about this cyclization to provide the desired isatogens and accommodate
封面图片显示了硝基炔环异构化导致 isatogens 的历史细节。自从 19 世纪后期 Baeyer 首次记录了该反应(显示了 Baeyer 的图片和相应的文献引用)以来,人们一直在寻求一种温和的通用方法来合成 isatogens。亲电性 PdII 卤化物复合物被发现会引起这种环化作用,以提供所需的色素原,并容纳芳基和烷基取代基,并能耐受常用的保护基团/功能单元。CV Ramana、K. Vanka、A. Degterev 等人在文章中讨论了通过高级理论研究的反应过程的细节以及作为新 ROS(活性氧)清除剂的靛蓝素的用途。阿尔。在页。第 5955 章
