rhodium-catalyzed decarbonylative aerobic oxidation of cyclic α-diketones has been developed for the first time, where the regioselective formations of α-pyrones and isocoumarins have been achieved. The current decarbonylative aerobic oxidation pathway proceeds via the C–C bond cleavage followed by a C–O bond formation, representing a biomimetic oxidation approach to unsaturated six-membered cyclic
首次开发了铑催化的环状α-二酮的去羰基好氧氧化反应,在该反应中已经实现了α-吡喃酮和异香豆素的区域选择性形成。当前的脱羰需氧氧化途径是通过C–C键断裂,然后形成C–O键进行的,这代表了对不饱和六元环内酯的仿生氧化方法。铑催化剂具有独特的诱导脱羰需氧氧化的能力,从而开辟了利用“区域选择性单碳”挤出策略的新型合成工具箱。
