We report a new simple method to accesshighly substituted cyclopentanes via Lewis acid-initiated formal [3 + 2]-cycloaddition of donor–acceptor cyclopropanes to 1,3-dienes. This process displays exceptional chemo- and regioselectivity as well as high diastereoselectivity, allowing for the synthesis of functionalizedcyclopentanes and bicyclic cyclopentane-based structures in moderate to high yields
