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.

Treatment of β-aryl-β-(benzotriazol-1-yl)-α-primary alkyl (or aryl)-α,β-unsaturated ketones 1 with n-Bu3SnH (4 equiv) in a catalytic amount of AIBN in PhH at reflux afforded 3-alkyl (or aryl)-2-arylindoles 8 in good yields. However, when tert-butyl group is bonded at α-position, 3-acyl (or aroyl)-2-arylindoles 9 were obtained as major products along with phenanthridines 5 as minor products.
