A simple and 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 Pravadoline, a phase II analgesic drug.

In the present study, a novel synthetic strategy to directly produce 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.

The synthesis of 3-acyl-2-arylindole derivatives was performed through palladium-catalyzed isocyanide insertion and oxypalladation of an alkyne. As a result of the introduction of internal nucleophiles, domino cyclization was also achieved for the synthes
