Catalyst‐Controlled Regiodivergent Alkyne Insertion in the Context of C−H Activation and Diels–Alder Reactions: Synthesis of Fused and Bridged Cycles

Angewchem
Catalyst‐Controlled Regiodivergent Alkyne Insertion in the Context of C−H Activation and Diels–Alder Reactions: Synthesis of Fused and Bridged Cycles: Rhodium(III)‐ and cobalt(III)‐catalyzed C−H activation of indoles and coupling with 1,6‐enynes is discussed. Under rhodium(III) catalysis, the alkyne insertion follows 2,1‐regioselectivity with a subsequent...
