Bond activation in action: Unprecedented ruthenium‐catalyzed oxidative annulations of alkynes through cleavage of CH bonds set the stage for an efficient 1(2H)‐isoquinolone synthesis with ample scope (see scheme; tAm=tert‐amyl). Mechanistic studies provided strong evidence for a rate‐limiting CH bond metalation through carboxylate assistance.
键活化在动作:以C裂解炔烃的前所未有的钌催化氧化annulations H键设置阶段为一个有效的1(2 ħ)-isoquinolone合成了充足的范围(参见方案;吨AM =叔戊基)。机理研究为通过羧酸盐协助限速CH键金属化提供了有力证据。
