Amberlyst-15: A mild, efficient and reusable heterogeneous catalyst for Michael addition of pyrroles to alpha,beta-unsaturated ketones
A general procedure for the Michael addition of pyrroles with alpha,beta-unsaturated ketones using catalytic amount of Amberlyst-15 at room temperature has been developed. This method is fast, efficient, high yielding and eco-friendly to afford the corresponding Michael adducts generally in good to excellent yields without polymerization. (c) 2007 Elsevier B.V.
