Abstract
A gold-catalyzed synthesis of 1-bromo/chloro-2-carboxy-1,3-dienes is developed using propargylic carboxylates containing halogenated alkynes as substrates. The reaction is highly diastereoselective, and the halogen atom at the alkyne terminus selectively promotes a 1,2-acyloxy migration. The diene products participate in the Diels-Alder and cross-coupling reactions.
