and one-pot procedure for the synthesis of arylated and stereodefined allylic alcohols has been achieved through zirconium-mediated multicomponent coupling reactions of alkynes, aldehydes (or ketones), and aryl iodides. The subsequent intramolecular Friedel-Crafts reactions of these allylic alcohols catalyzed by Bronsted or Lewis acids afford highly substitutedindenes and spiroindenes under extremely
