Indium(111) bromide-catalyzed hydroarylation of alkynes with indoles leading to the synthesis of 3-vinylincloles in good to excellent yields was achieved. The E/Z ratio of the products depends on the substituents on the indole. This protocol is efficient and atom-economic from the synthetic point of view. (C) 2010 Elsevier Ltd. All rights reserved.
Diastereoselective synthesis of 3-(α-aryl)alkenylindoles from the direct dehydrative coupling of indoles and ketones: A synthetic and theoretical study
A representative library of 3-(α-aryl)alkenylindoles has been prepared via a Brønsted-acid catalysed dehydrative coupling reaction between alkyl aryl ketones and some indoles. An interesting diastereoselectivity has been observed and has been explained from a mechanistic point of view.
