Batting the ylides: A simple procedure carried out under mild conditions allows the direct and efficientsynthesis of structurally diverse indoles. This approach involves a cascadereaction of sulfurylides and N‐(ortho‐chloromethyl)arylamides (see scheme).
N-Phenacyl- and N-acetonyl-isatins can be prepared and converted by treatment with sodium hydroxide into 2-acylindoles and/or 2-acyl indole-3-carboxylic acids.

A simple synthesis of 2-aroylindoles via palladium-catalyzed tandem oxidative annulation directly from α-amino ketones has been developed. In this transformation, two-step reaction including oxidation of α-amino aetones to generate imine intermediates and subsequent palladium-catalyzed aerobic annulation to give 2-aroylindoles was compatible in onepot.

An organocatalytic enantioselective formal hydroarylation of 2-vinyl indoles for the preparation of enantioenriched 2,3′-bis(indolyl)methanes bearing an all-carbonquaternarystereocenter is described. This reaction features mild conditions, low catalyst loading, excellent efficiency and enantioselectivity. The obtained products showed promising anticancer activity.
