inexpensive, nontoxic manganese catalyst enabled unprecedented redox‐neutral carbonylative annulations under ambient pressure. The manganese catalyst outperformed all other typically used base and precious‐metal catalysts. The outstanding versatility of the manganese catalysis manifold was reflected by ample substrate scope, setting the stage for effective late‐stage manipulations under racemization‐free
廉价,无毒的锰催化剂可在环境压力下实现前所未有的氧化还原中性羰基环化反应。锰催化剂的性能优于所有其他常用的碱金属和贵金属催化剂。充足的底物范围反映了锰催化歧管出色的多功能性,为在无消旋条件下对许多市售药物和天然产物(包括生物碱,氨基酸,类固醇和碳水化合物)进行有效的后期操作奠定了基础。
