title: Organocatalytic C3-selective Friedel-Crafts alkylations of indoles with alpha,beta-unsaturated ketones.
abstract: The use of an equimolar amount of pyrrolidine and HClO4 (30 mol%) was found to be effective in promoting the conjugate addition of indoles to (E)-alpha,beta-unsaturated ketones, affording the corresponding beta-indolyl ketones in excellent yields.
