An efficient PhIO-mediated oxidative C═C bond cleavage and reassembly of enaminone toward oxazolone with high regioselectivity has been reported. DFT calculations revealed that the reaction proceeded through an oxygen atom transfer, C═C bond cleavage, alkylthio migration, and reassembly cascade. This strategy is highlighted by high atom and step economy with formation of five bonds in one pot and generation of a high-valued oxazolone skeleton under mild conditions.
据报道,一种高效的PhIO介导的烯胺酮氧化碳-碳键断裂并以高区域选择性重排生成恶唑酮的反应。密度泛函理论计算表明,该反应通过氧原子转移、碳-碳键断裂、烷硫基迁移和重排级联进行。该策略的突出特点是具有高原子经济性和步骤经济性,能够在温和条件下一步形成五个化学键,并生成高价值的恶唑酮骨架。
