## Abstract A novel Lewis acid‐catalyzed [3+4] annulation of 2‐(heteroaryl)cyclopropane‐1,1‐dicarboxylates with cyclopentadiene is reported. This reaction proceeds __via__ an electrophilic attack of the Lewis acid‐activated donor‐acceptor cyclopropane onto cyclopentadiene followed by Friedel–Crafts
We have recently shown that the aluminum chloride catalyzed reaction of propiolate esters with alkenes yields stereospecific [2+23 cycloadducts and/or ene adducts, depending on the degree of substitution of the double bond?sUnlike other aluminum chloride catalyzed [2+2] cycloaddition reactions of ac
