title: Acid-catalyzed skeletal rearrangement of epoxy alkynes: a fast access to highly functionalized allenes.
abstract: The acid-catalyzed reaction of epoxy alkyne involves an epoxide ring-opening attacked by pi-alkyne, leading to a semipinacol-type rearrangement. In this process, a type of carbon-carbon 3,3-migration of the alkyne system has been discovered, which is promoted both by epoxide inducing and hydroxide promoting. This transformation enables the fast synthesis of allenes in mild conditions.
