Divergent Synthesis of 2‐Quinolinones and Indolin‐3‐ones via Mo‐Catalyzed Controllable Carbonyl Deoxygenative Coupling and Formal Deoxygenative N—H Insertion Reactions

Comprehensive Summary The divergent synthesis of 2‐quinolinones and indolin‐3‐ones through unprecedented Mo‐catalyzed controllable carbonyl deoxygenative coupling and formal deoxygenative N—H insertion reactions was reported. By simply changing the molybdenum catalytic conditions, both product categories were produced in generally good yields and with high chemoselectivities from the same starting materials. This strategy was robust, convenient and ready for the rapid construction of diverse product libraries.
