Cycloaddition reactions of trimethylenemethane diyls generated from alkynyl iodonium salts

Intramolecular [2+3] cycloaddition reaction of trimethylenemethane diyls that were generated successfully from the reaction of malonate anions containing diene units with propynyl iodonium salts via alkylidene carbene intermediates produced linearly fused triquinanes.
