Conjugate Addition of Indoles to α,β-Unsaturated Ketones Using a Brønsted Acid Ionic Liquid as an Efficient Catalyst
The Brønsted acid ionic liquid [PyN(CH2)4SO3H][p-CH3PhSO3] has been reported as an efficient catalyst for the Michael addition reaction of indoles to α,β-unsaturated ketones. Satisfactory results were obtained, with excellent yields and a simple experimental procedure. The catalyst could be recycled...
