Abstract
We described herein a Rh(III)-catalyzed C7-selective CH activation/annulation of indolines with 1,3-enynes to efficiently access various privileged 1,7-fused indolines bearing an all-carbon quaternary stereogenic carbon center. Notably, the resulting products can be readily transformed into 1,7-fused indoles, further widening the C-7 derivatization of indoles and highlighting the synthetic utility of this methodology.
