The indium(III)-catalyzed enantioselective and regioselective addition of pyrroles to isatins is described. The effects of metal and solvent on the reactivity and selectivity are compared and discussed, demonstrating that the indium(III)-indapybox complex provides the most effective catalyst. A case of divergent reactivity between pyrroles and indoles is presented.
本文描述了铟(III)催化吡咯与色酮的对映选择性和区域选择性加成反应。比较和讨论了金属和溶剂对反应活性和选择性的影响,结果表明,铟(III)-吲哚啉酮配合物提供了最有效的催化剂。还提出了吡咯和吲哚之间反应活性差异的情况。
