Lewis acid-catalyzed intramolecular [3+2] cycloaddition of cyclopropane 1,1-diesters with alkynes for the synthesis of cyclopenta[c]chromene skeletons

An efficient method to construct cyclopenta[c]chromene skeletons by Lewis acid-catalyzed intramolecular [3+2] cycloaddition of cyclopropane 1,1-diesters with alkynes is presented. Two new fused cycles can be formed in one step in moderate to excellent yie
