investigations are consistent with an oxidative addition/olefin insertion/reductive elimination mechanism. The incorporated methylene sulfide substituent can undergo a variety of further reactions to increase molecular diversity and complexity. These results demonstrate that thioester derivatives can be used as powerful building blocks for the assembly of complex scaffolds.
已开发出镍催化的硫代酸酯与烯烃的分子内偶联,可有效合成螺环,螺环是天然产物中常见的一种特权支架。这种转化的特征是酰基和硫醇基团同时转移到烯烃上,同时抑制了脱羰基作用和β-氢消除。最初的机理研究与氧化加成/烯烃插入/还原消除机理一致。掺入的亚甲基硫取代基可进行多种进一步的反应以增加分子多样性和复杂性。这些结果表明,硫酯衍生物可以用作组装复杂支架的有力基础。
