title: Gold-catalyzed rearrangement of alkynyl donor-acceptor cyclopropanes to construct highly functionalized alkylidenecyclopentenes.
abstract: A gold-catalyzed 1,7-addition-cyclization-elimination cascade sequence performed on a range of alkynyl-substituted donor-acceptor-type cyclopropanes provides facile entry to highly functionalized exo-alkylidenecyclopentenes under very mild conditions. Isolation of the relevant allyl ether intermediate helped shed light on the reaction's mechanistic course.
