Abstract

A new type of TfOH-catalyzed tandem cyclopropane ring enlargement/C–C formation/etherification reaction between alkynylcyclopropanes and 1,3-diketones to cyclobutane-fused dihydrofurans is described. The reaction tolerates a range of aryl and alkyl substituents with moderate to good yields.
