摘要：

Herein, using electron-deficient alkenes embedded with an oxidizing function/leaving group as a rare and nontraditional C-1 synthon, we have achieved the redox-neutral Rh(iii)-catalyzed chemo- and regioselective [4 + 1] annulation of benzamides for the synthesis of functionalized isoindolinones. This method features broad substrate scope, good to excellent yields, excellent chemo- and regioselectivity, good tolerance of functional groups and mild external-oxidant-free conditions.
