versatile 3-acylindoles through Rh(III)-catalyzed C–H activation and annulation cascade of N-phenylamidines with α-Cl ketones was developed, in which α-Cl ketones serve as unusual one-carbon (sp3) synthons. This strategy features high regioselectivity, efficiency, wide substrate tolerance, and mild reaction conditions, which further underscore its synthetic utility in drug molecule synthesis.

efficient strategy for the preparation of 3‐acylindoles via palladium‐catalyzed cyclization reaction of N‐(2‐haloaryl)alkynylimines in water has been developed. The reaction tolerates a wide range of functional groups, and the corresponding 3‐acylindoles were obtained in high yields using water as the sole solvent and oxygen sources. Additionally, this method could provide a short synthesis route for
